the J1 byte. TNULL should be set high before changing the contents of the

trace buffer to avoid sending partial messages.

PER5:

The PER5 bit controls the number of times a path trace identifier message

must be received unchanged before being accepted. When PER5 is a logic

one, a message is accepted when it is received unchanged five times

consecutively. When PER5 is a logic zero, the message is accepted after

three identical repetitions.

RTIMIE:

The RTIMIE bit controls the activation of the interrupt output when the

comparison between accepted identifier message and the expected message

changes state. When RTIMIE is a logic one, changes in match state activates

the interrupt (INTB) output.

RTIUIE:

The RTIUIE bit controls the activation of the interrupt output when the receive

identifier message changes state. When RTIUIE is a logic one, changes in

the received path trace identifier message stable/unstable state activates the

interrupt output.

RRAMACC:

The RRAMACC bit directs read and writes access to either the receive or

transmit path trace buffer. When RRAMACC is a logic one, microprocessor

accesses are directed to the receive path trace buffer. When RRAMACC is a

logic zero, microprocessor accesses are directed to the transmit path trace

buffer.
