TMS/TXER{1}

IPD

Test Mode Select. This pin becomes TMS if TRST is high.

Single control input to the JTAG TAP controller is used to

traverse the test-logic state machine. Sampled on the rising

edge of TCK.

TDO/PAUSE{1}

O3S

Test Data Output. This pin becomes TDO if TRST is high.

Serial data output from the JTAG TAP controller. Updated on

the falling edge of TCK.
