Test Mode Select. The TMS pin is sampled by the TAP on the rising
edge of TCK. The TAP state machine uses the TMS pin to deter-
mine the mode in which the TAP operates.

O/I/O
Trace Status 3 / Data Parity 3. When parity checking and generation
are enabled, this signal represents odd parity for read/write opera-
tions using byte 3 (D24:31) of the data bus. The Parity Error status
bit is set in the BESR when a parity error is detected.
