Mute..............Setting this bit to “1” mutes both left and right channels of the ZV port.
MSEL ...........This bit is read only, and indicates the status of No.40 MSEL pin.
“0” : Low
“1” : High
GL4-0 ...........These bits determine the volume level of the ZV port left channel by 1.5dB step. The volume
range is from +12dB to -34.5dB. When all bits are set to “0”, volume is maximum (+12dB) and
when all bits are set to “1”, volume is minimum (-34.5dB).
ZEN ..............This bit selects whether ZV port is used or not.
“0” : ZV port is power down state, and can not be used.
“1” : ZV port can be used.
ZAC ..............This bit is read only, and indicates whether the bit clock (ZV_BCK) is input to ZV port or not.
“0” : The bit clock (ZV_BCK) is not input.
“1” : ZV port is active because the bit clock (ZV_BCK) is input.
GR4-0 ...........These bits determine the volume level of the ZV port right channel by 1.5dB step.
Setting to them is the same as the upper GL4-0 bits.

TX-3 .............SPDIF signal is output from No.43 DIT, if this bit is set to “1” at MSEL= “Low”.
TX-8 .............SPDIF signal is output from No.48 DIT, if this bit is set to “1” at MSEL= “Low”.
DMU.............Setting this bit to “1” mutes audio data output from DIT.
UDS ..............This bit selects the data output from DIT.
“0” : Data from the AC-Link
“1” : Data from A/D converter
3AWE ...........This bit selects whether 3Ah register can be written or not.
“0” : 3Ah register is Read Only.
“1” : 3Ah register is Read / Write.
D8, D7, D6 and D4 should not be changed from the default value.
