#
All registers not shown and bits containing an X are reserved.
Any reserved bits, marked X, are not writable, and read back as zeros.
PC_BEEP default to 0000h, un-muted.
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 1Fh as a value for this attenuation/gain block.
