The receive trace identifier persistence bit (PER5) control the number of times a section
trace identifier message must be received unchanged before being accepted. When PER5 is
set high, a message is accepted when it is received unchanged five times consecutively.
When PER5 is set low, the message is accepted after three identical repetitions.
The RTIMIE bit controls the activation of the interrupt output when the comparison
between the trace identifier mode 1 accepted identifier message and the expected message
changes state. When RTIMIE is a logic one, changes in match state activates the interrupt
(INTB) output.
This register is ignored when TIMODE is set high.
The RTIUIE bit controls the activation of the interrupt output when, in either trace identifier
mode, the receive identifier message changes state. When RTIUIE is a logic one, changes
in the received section trace identifier message stable/unstable state will activate the
interrupt (INTB) output.
The trace identifier mode is used to set the mode used for the received trace identifier.
Setting TIMODE low sets the trace identifier mode to 1. In this mode, the trace identifier is
defined as a regular 16 or 64 byte trace message and persistency is based on the whole
message. Receive trace identifier mismatch (RTIM) and unstable (RTIU) alarms are
declared on the trace message.
Setting TIMODE high set the trace identifier mode to 2. In this mode, the trace identifier is
defined as a single byte that is monitored for persistency and then errors. A receive trace
identifier unstable (RTIU) alarm is declared when one or more errors are detected in three
consecutive 16 byte windows.
For trace identifier mode 1 only, the zero enable bit (ZEROEN) enables TIM assertion and
removal based on an all ZERO’s section trace message string. When ZEROEN is set high,
all ZERO’s section trace message strings are considered when entering and exiting TIM
states. When ZEROEN is set low, all ZERO’s section trace message strings are ignored.
This register is ignored when in trace identifier mode 2 (controlled by TIMODE).
