 Details
Timer Interface Module (TIM1 and TIM2)
10.12 Timer Interface Module (TIM1 and TIM2)
10.12.1 Wait Mode
The timer interface modules (TIM) remain active in wait mode. Any enabled CPU interrupt request from
the TIM can bring the MCU out of wait mode.
If TIM functions are not required during wait mode, reduce power consumption by stopping the TIM before
executing the WAIT instruction.
10.12.2 Stop Mode
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.
10.13 Timebase Module (TBM)
10.13.1 Wait Mode
The timebase module (TBM) 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.
10.13.2 Stop Mode
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 OSCENINSTOP bit in the CONFIG2 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.
10.14 MSCAN
10.14.1 Wait Mode
The MSCAN module remains active after execution of the WAIT instruction. In wait mode, the MSCAN08
registers are not accessible by the CPU.
If the MSCAN08 functions are not required during wait mode, reduce the power consumption by disabling
the MSCAN08 module before enabling the WAIT instruction.
10.14.2 Stop Mode
The MSCAN08 module is inactive in stop mode. The STOP instruction does not affect MSCAN08 register
states.
Because the internal clock is inactive during stop mode, entering stop mode during an MSCAN08
transmission or reception results in invalid data.
