6.2.3.2 Peripheral Usage in Sleep

Some peripherals that can operate in Sleep mode will not operate properly with the Low-Power Sleep mode selected. The Low-Power Sleep mode is intended for use with these peripherals:

  • Brown-out Reset (BOR)
  • Windowed Watchdog Timer (WWDT)
  • External interrupt pin/Interrupt-On-Change pins
  • Peripherals that run off external secondary clock source

It is the responsibility of the end user to determine what is acceptable for their application when setting the VREGPM settings in order to ensure operation in Sleep.
