Break Module (BREAK)
15.3.1 Flag Protection During Break Interrupts
The system integration module (SIM) controls whether or not module status bits can be cleared during
the break state. The BCFE bit in the break flag control register (BFCR) enables software to clear status
bits during the break state. (See
subsection for each module.)
15.3.2 CPU During Break Interrupts
The CPU starts a break interrupt by:
The break interrupt begins after completion of the CPU instruction in progress. If the break address
register match occurs on the last cycle of a CPU instruction, the break interrupt begins immediately.
15.3.3 TIM During Break Interrupts
A break interrupt stops the timer counter.
15.3.4 COP During Break Interrupts
The COP is disabled during a break interrupt when V
