Data Sheet
366
The BCFE bit in the SIM break flag control register (SBFCR) enables
software to clear status bits during the break state.
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 counters.
The COP is disabled during a break interrupt when V
the RST pin.
The WAIT and STOP instructions put the MCU in low power-
consumption standby modes.
If enabled, the break module is active in wait mode. In the break routine,
the user can subtract one from the return address on the stack if SBSW
is set (see
SBSW bit by writing logic 0 to it.
