Technical Data
206
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
RST pin.
The WAIT and STOP instructions put the MCU in low power-consump-
tion standby modes.
If enabled, the break module is active in wait mode. The SIM break wait
bit (BW) in the SIM break status register indicates whether wait was
exited by a break interrupt. If so, the user can modify the return address
on the stack by subtracting one from it. (See
on page 166).
