Low-Power Modes
Timer Interface Module (TIM1 and TIM2)
3.12.2 Stop Mode
The SPI module is inactive in stop mode. The STOP instruction does not
affect SPI register states. SPI operation resumes after an external
interrupt. If stop mode is exited by reset, any transfer in progress is
aborted, and the SPI is reset.
3.13 Timer Interface Module (TIM1 and TIM2)
3.13.1 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.
3.13.2 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.
3.14 Timebase Module (TBM)
3.14.1 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.
