AMP

Power down Class D amplifier. Configures the power state of the Class D amplifier.

0 (Default) Powered up

1 Powered down

3:2

Power-down boost converter. Configures the power state of the boost converter.

00 Powered up

01 (Default) Boost Mode bypass. Turns the boost FET OFF, the rectifying FET ON, and the remaining boost circuitry in a low-

power state, with VBST = VP. Powers down internal-control circuitry when operating in VBST = VP Mode.

0PDN_

ALL

Power down all. Configures the CS35L32 power state. Can be used to quickly power down the device but is not equivalent to

using all of the individual power-down bits.

0 (Default) Powered up, as per individual controls in power control registers 1 and 2.

1 Powered down. All affected blocks are powered down, regardless of individual power-down bit settings.
