NOTE:
The STOP, HALT, and WAIT instructions put the MCU in low-power
consumption standby modes.
The STOP instruction clears the COP watchdog counter. Upon exit from
stop mode by external reset:
Upon exit from stop mode by external interrupt:
Halt mode is NOT designed for intentional use. Halt mode is only
provided to keep the COP watchdog timer active in the event a STOP
instruction is executed inadvertently. This mode of operation is usually
achieved by invoking wait mode.
Execution of the STOP instruction when STOP is disabled mask option
is selected placing the MCU in this low-power mode. Halt mode
consumes the same amount of power as wait mode (both halt and wait
modes consume more power than stop mode).
Upon exit from halt mode by COP reset or external reset:
