25.3.3.2
The current context ID register (CCIDR) shown in
register is written by software after a context switch and can be used to trigger events when compared with
the programmed context ID register (PCIDR).
Table 25-24
25.3.4
TRIG_OUT provides a convenient mechanism for triggering external system monitors and diagnostic
equipment such as logic analyzers. Note that READY is multiplexed with TRIG_OUT. See the last
paragraph of
functionality.
When the trace buffer hit is selected by TOSR[SEL], TRIG_OUT is only meaningful if the trace buffer
control register 0 (TBCR0) is properly configured to hit on a traceable event. The same holds true for the
watchpoint monitor when the watchpoint monitor is selected by TOSR[SEL].
25.3.4.1
The trigger out source register (TOSR) shown in
three event-trigger sources are the following:
