Operating Modes
6.5 COP Watchdog Timer Considerations
Technical Data
54
NOTE:
If the 16-bit timer interrupt is enabled, it causes the processor to exit wait
mode and resume normal operation. The 16-bit timer may be used to
generate a periodic exit from wait mode. Wait mode may also be exited
when an IRQ or RESET occurs.
If port A interrupts are selected as a mask option, the processor also will
exit wait mode.
The COP watchdog timer is active in the user mode of operation when
selected by mask option. Executing the STOP instruction without
conversion to halt via mask option causes the COP to be disabled.
Therefore, it is recommended that the STOP instruction be modified to
produce halt mode via mask option if the COP watchdog timer is
enabled.
Furthermore, it is recommended that the COP watchdog timer be
disabled for applications that use the halt or wait mode for time periods
that exceed the COP timeout period.
