For embedded developers and hardware hackers, JTAG is the de facto standard for debugging and accessing microprocessor registers. This protocol has been in use for many years and is still in use today. Its main drawback is that it uses a lot of signals to work (at least 4 – TCK, TMS, TDI, TDO). WebbTDI is sampled on the rising edge of TCK and should be driven on the falling-edge of TCK. TDI pins have internal weak pull-up resistors.
