Periodic Modes
These modes allow autonomous power on/off control with reduced fix rate to decrease average
power consumption. The main power supply pin VCC_ON is still powered, but power distribution
to internal circuits is internally controlled by the receiver.
STANDBY(SLEEP): ARM baseband and RF are powered down.
BACKUP: ARM baseband, RF, and TCXO are powered down. RTC is powered up.
