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.
