JTAG Specification
These products support a limited set of JTAG functions as in IEEE standard 1149.1.
Test Access Port (TAP) Pins
Remark The device does not have TRST (TAP reset). The Test-Logic Reset state is entered while TMS is held HIGH

Test Clock Input. All input are captured on the rising edge of TCK and all outputs
Test Mode Select. This is the command input for the TAP controller state machine.
Test Data Input. This is the input side of the serial registers placed between TDI and
Test Data Output. This is the output side of the serial registers placed between TDI and
propagate from the falling edge of TCK.
TDO. The register placed between TDI and TDO is determined by the state of the TAP
controller state machine and the instruction that is currently loaded in the TAP instruction.
TDO. Output changes in response to the falling edge of TCK.
