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.
