PDC: This bit is used for the CODEC power-down control. For making this bit valid, "0"s must be written to the control data bits
described in the later section.
PDC = 1: CODEC is in power-down mode. PDC = 0: CODEC is in operation mode.
When the HOW is indicated, the LOSS output is "1". Otherwise it is "0".
In the above specification, the data contents written later are valid. The signal of sounder path (SA0, SA1) and the signal of receive path
(RPO) can not be output simultaneously.
