TDO
register. Data is shifted out of the device on the negative edge of the TCK
signal.
TMS
TAP state machine.
TCK
and TDI pins. It is a positive edge triggered clock with the TMS and TCK
signals that define the internal state of the device.
TRSTNInput Test Reset N. This signal resets the JTAG controller.
RTCK OutputReturn Clock. This is a synchronization signal which the
JTAG connector uses to acknowledge it is ready to receive/transmit.
JTAG is used to to program and debug the MCU.
Input Test Data In. This is the serial data input for the shift
OutputTest Data Out. This is the serial data output for the shift
Input Test Mode Select. The TMS pin selects the next state in the
Input Test Clock. This allows shifting of the data in, on the TMS
