3.5.2 MSPM0 Capabilities in Lower Power Modes

As seen in Table 3-10, MSPM0 peripherals or peripheral modes can be limited in availability or operating speed in lower power operating modes. For specific details, see the "Supported Functionality by Operating Mode" table found in the MSPM0 device-specific data sheet, for example:

MSPM0G350x Mixed-Signal Microcontrollers data sheet

MSPM0L134x, MSPM0L130x Mixed-Signal Microcontrollers data sheet

MSPM0C110x Mixed-Signal Microcontrollers data sheet

An additional capability of the MSPM0 devices is the ability for some peripherals to perform an Asynchronous Fast Clock Request. This allows MSPM0 device to be in a lower power mode where a peripheral is not active, but still allow a peripheral to be triggered or activated. When an Asynchronous Fast Clock Request happens, the MSPM0 device has the ability to quickly ramp up an internal oscillator to a higher speed and/or temporarily go into a higher operating mode to process the impending action. This allows for fast wake up of the CPU from timers, comparator, GPIO, and RTC; receive SPI, UART, and I2C; or trigger DMA transfers and ADC conversions, while sleeping in the lowest power modes. For specific details on implementation of Asynchronous Clock Requests as well as peripheral support and purpose, see the appropriate chapter in the device-specific MSPM0 TRMs.
