The WAIT and STOP instructions put the MCU in low power-
consumption standby modes.
The timebase module remains active after execution of the WAIT
instruction. In wait mode the timebase register is not accessible by the
CPU.
If the timebase functions are not required during wait mode, reduce the
power consumption by stopping the timebase before executing the
WAIT instruction.
The timebase module may remain active after execution of the STOP
instruction if the internal clock generator has been enabled to operate
during stop mode through the OSCENINSTOP bit in the configuration
register. The timebase module can be used in this mode to generate a
periodic wake up from stop mode.
If the internal clock generator has not been enabled to operate in stop
mode, the timebase module will not be active during stop mode. In stop
mode, the timebase register is not accessible by the CPU.
If the timebase functions are not required during stop mode, reduce
power consumption by disabling the timebase module before executing
the STOP instruction.
