RTIMIE:

The receive trace identifier mismatch interrupt enable (RTIMIE) controls the

activation of the interrupt output when comparison between the accepted

trace identifier message and the expected trace identifier message changes

state from match to mismatch and vice versa. When RTIMIE is set high,

changes in match state will activate the interrupt output. When RTIMIE set

low, trail trace message match state changes will not affect INTB.

RTIUIE:

The receive trace identifier unstable interrupt enable (RTIUIE) control the

activation of the interrupt output when the receive trace identifier message

changes state from stable to unstable and vice versa. When RTIUIE is set

high, changes in the state of the trail trace message unstable indication will

activate the interrupt output. When RTIUIE set low, trail trace unstable state

changes will not effect INTB.

RRAMACC:

The receive RAM access (RRAMACC) control bit is used by the

microprocessor to identify that the access from the microprocessor is to the

receive trace buffers (addresses 0 - 127) or to the transmit trace buffer

(addresses 128 - 191). When RRAMACC is set high, subsequent

microprocessor read and write accesses are directed to the receive side trace

buffers. When RRAMACC is set low, microprocessor accesses are directed

to the transmit side trace buffer.

ZEROEN:

The zero enable bit (ZEROEN) enables TIM assertion and removal based on

an all ZEROs path trace message string. When ZEROEN is set high, all

ZEROs path trace message strings are considered when entering and exiting

TIM states. When ZEROEN is set low, all ZEROs path trace message strings

are ignored.
