Following a reset, ensure that the clock register (0x00) is written before performing volume, treble, or bass
updates.
Commands to reconfigure the SAP can be accompanied by mute and unmute commands for quiet
operation. However, care must be taken to ensure that the mute command has completed before the SAP
is commanded to reconfigure. Similarly, the TAS3204 should not be commanded to unmute until after the
SAP has completed a reconfiguration. The reason for this is that an SAP configuration change while a
volume or bass or treble update is taking place can cause the update not to be completed properly.
When the TAS3204 is transmitting serial data, it uses the negative edge of SCLK to output a new data bit.
The TAS3204 samples incoming serial data on the rising edge of SCLK.
