Notes:
1.
All registers not shown and bits containing an X are reserved.
2.
Any reserved bits, marked X, can be written to but are don’t care upon read back.
3.
PC_BEEP default to 0000h, mute off.
4.
If optional bits D13, D5 of register 02H or D5 of register 06h are set to 1, then the corresponding attenuation
is set to 46dB and the register reads will produce 3Fh as a value for this attenuation/gain block.
