b11..............PSIO: Power Save I/O Pad
b12..............PSHWV: Power Save Hardware Volume
Setting this bit to “1” cuts the pull up resistor of the input pins except for the PCI interface and AC-Link.
The input signals keep the level before PSIO bit is set from “0” to “1”. In case the input level is only
“low”, the pull up resistor is cut.
Setting this bit to “1” stops a clock supplied to the Hardware Volume block.
“0”: Normal
“1”: Cuts the pull up resistor
“0”: Normal
“1”: Disable
