Device Functional Modes

The device has four main operating modes: Normal mode, Standby mode, Silent mode and Sleep mode, and one transitional mode called Go-to-Sleep mode. Operating mode selection is made via the nSTB and EN input terminals in conjunction with supply conditions and wake events.

Go-to-sleep: Transitional mode for EN = H, nSTB = L until tgo_to_sleep timer has expired
The INH pin transitions to high Z (off) after tgo_to_sleep timer has expired
Mode change from Go-to-Sleep mode to sleep mode once tgo_to_sleep timer has expired
