13.8 Low-Power Modes

13.8.1 Wait Mode

13.8.2 Stop Mode

13.9 COP Module During Break Mode

Advance Information
212
The WAIT and STOP instructions put the MCU in low-power
consumption standby modes.
The COP continues to operate during wait mode. To prevent a COP
reset during wait mode, periodically clear the COP counter in a CPU
interrupt routine.
Stop mode turns off the CGMXCLK input to the COP and clears the SIM
counter. Service the COP immediately before entering or after exiting
stop mode to ensure a full COP timeout period after entering or exiting

stop mode.

The COP is disabled during a break interrupt when V
on the RST pin.
