AUDIO
– AUDIO CONTROL REGISTERS
The Audio Class-D Module can be controlled and monitored by writing 8-bit control words to the various Registers as
described below. The Base addresses are defined in Table 3 – Register Address Global Mapping on page 20.
2.15.1 AUDIO - RESERVED Registers
These registers are reserved. Do not write to them.

Write “1” to reset audio subsystem. Internal logic will reset this bit to
“0” after 250 ns.

Disabled state will put audio subsystem in low power state (analog in
standby and PLL shut-off).

2.15.3 AUDIO - DAC0 Volume Control Registers (DAC0x_VOL)
These registers manage the output signal volume for DAC0, Left and Right respectively.
The MSB, bit 7, of each register is the mute bit. When this bit is set, the output is silent.
There are 128 gain selections from 0 dB to -95.25 dB. The step size is 0.75 dB.
