4.2.4 BACKUP Low Power Mode

This is the lowest power operating mode. All oscillators are disabled except for the 8kHz and the 32kHz oscillator. The

32kHz oscillator is firmware controlled. SYS_OSC is gated off, so PCLK and HCLK are inactive. The CPU state is not

maintained.

Only the RTC can operate in BACKUP mode. The AoD and RAM retention can optionally be set to automatically disable (and

clear) themselves when entering this mode. RAM may be optionally retained. The amount of RAM retained is controlled by

appropriately setting the PWRSEQ_LPCN.ramret register bits.

BACKUP mode supports the same wakeup sources as DEEPSLEEP mode.

To immediately enter BACKUP mode, write GCR_PMR.mode = 0b100.

Figure 4-5, shows the clock control during BACKUP mode.
