Operating Modes
Five operating modes are supported by the APMC and offer different power consumption levels
and event response latency times.
• Normal Mode:
• Idle Mode:
• Slow Clock Mode:
• Standby Mode:
• Power-down Mode:
The Main Power supply is switched on; the ARM Core Clock is enabled and the peripheral
clocks are enabled according to the application requirements.
The Main Power is switched on; the ARM Core Clock is disabled and waiting for the next
interrupt (or a main reset); the peripheral clocks are enabled according to the application
requirements and the PDC transfers are still possible.
Similar to Normal Mode, but the Main Oscillator and the PLL are switched off to save power;
the device core and peripheral run in Slow Clock Mode; Note that Slow Clock Mode is the
mode selected after the reset.
A combination of the Slow Clock Mode and the Idle Mode, which enables the processor to
respond quickly to a wake-up event by keeping very low power consumption.
The Main Power supply is turned off at the external power source until a programmable
edge on the wake-up signal or a programmable RTC Alarm occurs.
