Notice)

1)Set D7, D6, D4 and D3 bits to “0”.

2)In the power save modes 1, 2, the OUTL/R pins will keep the VREF voltage. In the power down mode, VREF voltage slowly decays to ground on transition into this mode, and quickly returns to VREF on transition from this mode. During these modes (power save/down), master volume is automatically muted, so all audio sources cannot be heard. After resuming these modes, master volume is still muted.

3)The Joystick portion must be re-initialized by writing any value to the Joystick port after resuming from the power down/save mode.
