MOTOROLA
The system integration module (SIM) controls whether module status bits can be
cleared during the break state. The BCFE bit in the SIM break flag control register
(BFCR) enables software to clear status bits during the break state. (See
SIM Break Flag Control Register
module.)
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.
A break interrupt stops the timer counter.
The COP is disabled during a break interrupt when V
The WAIT and STOP instructions put the MCU in low power-consumption standby
modes.
If enabled, the break module is active in wait mode.
The break module is inactive in stop mode. The STOP instruction does not affect
break module register states.
