Technical Data
56
The TIM is inactive in stop mode. The STOP instruction does not affect
register states or the state of the TIM counter. TIM operation resumes
when the MCU exits stop mode after an external interrupt.
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 enabling the WAIT
instruction.
The timebase module may remain active after execution of the STOP
instruction if the oscillator has been enabled to operate during stop mode
through the OSCSTOPEN bit in the CONFIG register. The timebase
module can be used in this mode to generate a periodic wakeup from
stop mode.
If the oscillator 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 the
power consumption by stopping the timebase before enabling the STOP
instruction.
