15. Power modes
SX8722 has 3 operating modes:
15.1. Power modes transitions
Start-up from shutdown:
Start-up from sleep:
Sleep sequence:
Shutdown sequence:
The timing of the transition states depends mainly on the Xtal presence, the EEPROM presence and if the transition is
caused by an I2C command or by a pin signal (SLEEP, SHUT, RESET).
