POWER DOWN CONTROL

The WM8170 includes a separate power down pin, PDB. When this pin is taken low the whole device

is powered down and all internal registers maintain their currently programmed value. Setting the

PD0 bit in the Power Down 1 register can perform a similar power down operation. These two global

power downs are logically OR’d.

In addition to the above power down facilities the WM8170 contains seven other selective power

downs of individual sections of the device. Setting the appropriate bit in the Power Down 2 register,

as described in the Device Configuration section of this data sheet, will power down the particular

part of the circuit. These bits are logically ANDed so that any combination of the available device

sections can be powered down simultaneously
