The RA4 devices have several functions for reducing power consumption. These include setting clock
dividers, stopping modules, selecting power control mode in Normal mode, and transitions to low power
modes. Refer to the chapter “Low Power Modes” in the Hardware User’s Manual for more details.
RA4 MCUs support four different types of LPM depending on the MCU Group. These are:
• Sleep mode
• Software Standby mode
• Snooze mode
• Deep Software Standby mode.
