SWD, a kind of serial signal, has two signal lines: SWCLK and SWDIO. Its input/output is determined by the data of both parties involving data exchanging, which is Host and Target. It has the same JTAG Protocol of JTAG Bus and is upward compatible. Its data transmission speed can be up to 4Mbps under 50MHz since it takes the CPU Standard Bidirectional Line Protocol of ARM. Besides it also has internal debugger; the TMS and TCK line of JTAG interface will act as SWDIO and SWCLK signal line so as to provide dual-mode program.
