IC Interface


BDM (Background Debug Mode) is the signal interface which is used in the MCU or embedded system debugging. Currently it supports the majority of Freescale products, and can be used for system development, online debugging or programming, application download and online update. Because BDM control module is independent of the CPU, the BDM hardware command can be run with the CPU command concurrently.



HPI (Host Port Interface) is a transmission interface, which is designed for DSP by TI (Texas Instruments). Hereinto, with the help of HPI, the DSP C5000 series and DSP C6000 series can be used to control all kinds of resources. Specifically, the HPI can be divided into two kinds, HPI-8 and HPI-16, which are used to transmit the 8-bit data and 16-bit data respectively. At the same time, the HPI-8 and HPI-16 can be divided into the Standard Type and the Enhanced Type.



(Video Intro – How to measure the eSPI Bus)

Intel has developed a successor to the low pin count (LPC) bus called the Enhanced Serial Peripheral Interface Bus (eSPI).

Compared with systems using LPC, Intel hopes to reduce the number of pins required on the motherboard, with higher available throughput than LPC.

This video introduces users to record and decode eSPI signals. And export the package list to a text file.



When engineers analyzed the data of signal,it takes a lot of time to find the crucial problem, which they looked for through counting waveform to recode the signal. However, Zeroplus Logic Analyzer not only completely gathers all signal once but also auto-codes to the supplied special Protocol Analyzer encoding software. Moreover, it can supply integrated signal format content of every data for you, the content includes RESET、PRESENCE PULSE and DATA. You can customize the number of data bit (the range is 1~32bit) and the sampling position (the range is 1~32bit), in order to let user read the data in package more exact.


JTAG 2.0

The(JTAG:JOINT EUROPEAN TEST ACTION GROUP)was established by the Europe Institution in 1985, in order to research the test of volume circuit .
After cooperating with the North American ,The name was changed into JTAG(JOINT TEST ACTION GROUP).
The IEEE1194.1 testing interface and board scan structure [IEEE1149.1b 1194] were put out in base of JTAG 2.0 testing testing standards in 1990 , it also becomes the standards of ANSI(AMERICAN NATIONAL STANDARDS INSTITUTE ).
With the development of the science and technology , the transmission of the digital signal gluts our daily life,however,those signals need the corresponding development tools to make engineers successfully finish the development work.
It will help you to shorten the time of exploitation , improve exploitation products efficiency and unnecessarily add the instrument expense by using the Zeroplus Analyzer and Bus Automatic Decoding software .

With the development of science and technology, the transmission of digital sign has been flooding our life, while the engineer also need elative instrument tool of the sign to finish the exploration fluently.

*Signal require 18 channels above, not support on LAP-C 16 channel series.



Zeroplus Logic Analyzer supports the function of analyzing Protocol Analyzer 3-WIRE. It is mainly used on the sensor or the data transmission of clock chips.
With the development of the science and technology, the transmission of the digital signal is glutting our daily life; however, those signals need the corresponding development tools to make engineers successfully finish the development work.



When engineers analyzed the data in I2C signal or the presented errors during transmitting, it takes a lot of time to find the crucial problem, which they looked for through counting waveform to recode to the signal.

It can help you reduce the time of developing signal and improve the efficiency of developing new product to use Zeroplus Logic Analyzer and bus auto-coding software. You can supply your correlated information for us;Zeroplus will make the customized bus analysis software for you as your requirement.



The MDDI interface standard is intended for portable imaging equipment regulated by group of VESA (Video Electronics Standards Association) under the image signal equipment. It is based on the LVDS transmission technology, supporting transfer rate is up to 3.2Gbps. Using MDDI interface can reduce the number of connecting the signal lines to six, generally two data lines, one is for Stb, another one is for DATA. If multiple data, one is for Stb, the data lines were DATA0, DATA1,and thus reducing the noise interference problem.



MicroWire is usually used in EEPROM, DAC (Digital-to-Analog Converters) and ADC (Analog -to- Digital Converters), thereinto its signal structure is quite similar to SPI (Serial Peripheral Interface). MicroWire transmits data by serial mode, so when user analyzes data, it takes a lot of time to look for the problem, which user looks for by counting the waveform to do signal coding, and the process has to use oscillograph.
However, as to ZEROPLUS Logic Analyzer,it not only completely gathers the data once ,but also auto-decodes by the applied special bus coding software.



MIPI (Mobile Industry Processor Interface) Display Interface (DSI) is the definition of one Workgroup under MIPI Alliance. It is mainly used in the image signal transmission for display interface of mobile devices. Its two working modes, Low-power (LP) data mode and High-speed (HS) data mode which have different transmission speed and power, allows the MIPI to transmit at high speed if plenty of data is required to be transmitted or with low power consumption if little data is required. A pair of difference clocks and four pairs of difference data are used to do transmission.



Generally SPI Protocol Analyzer shows in two groups of data when it is used, the two groups of data are DATA IN/MISO and DATA OUT/MOSI;If enginee test signal with the normal two-channel oscillograph, it must need to test more than twice. First, we test MOS part, connect CS to EXTTRIG as trigger signal, then connect CH1 to DATA and CH2 to SCK, next test the MISO by the same step. If it need test MOSI again, the oscillograph should be connected again.



Zeroplus Logic Analyzer supports the function of analyzing Protocol Analyzer SLE4442. The names of SLE4442 and SLE4443 may be unfamiliar to a part of engineers, but they are used on the IC of Smart card; the familiar application of them is in finance cards, credit cards, health insurance cards and so forth.


SSI Interface

The familiar usage range of SSI Interface includes wireless communications transmission (instead of the company,such as MOTOROLA、NOKIA)、servo power management 、ADC transition、DAC transition and multimedia digital signal decoding (CODECS) and so on.



The Protocol Analyzer SPI is usually displayed with two groups of data mode (DATA IN/MISO and DATA OUT/MOSI) when it is used. If engineers use the most common oscillograph with two channels to measure the signal, they need to measure the signal more than two times. Firstly,they need to measure the MOSI part. When they measure the MOSI part, they need to connect the CS to EXTTRIG to work as the trigger signal, then connect the CH1 to DATA and CH2 to SCK. Secondly, they need to measure the MISO part according to the method of measuring the MOSI part. If engineers want to measure the MOSI part again at the moment, they need to connect the oscillograph to the original state. Obviously, it wastes a lot of time with the complex steps.
