The sleep mode of DRF4432D20 is realized through software. In sleep mode, the levels of

DRF4432S module remain the same status before entering sleep mode so the module can quickly

enter receive mode. The switching time from sleep mode to receive is about 20us. Please note that

the DRF4432S module only can enter into sleep mode after receive process is finished and the

AUX pin is kept in low.
