Low-Power Modes
Serial Peripheral Interface Module (SPI)
Serial Peripheral Interface Module (SPI)
Wait Mode
The SPI module remains active in wait mode. Any enabled CPU interrupt
request from the SPI module can bring the MCU out of wait mode.
If SPI module functions are not required during wait mode, reduce power
consumption by disabling the SPI module before executing the WAIT
instruction.
The DMA can service the SPI without exiting wait mode.
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.
Timer Interface Module (TIM)
Wait Mode
The TIM remains 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.
The DMA can service the TIM without exiting wait mode.
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.
