from the ADC output.

TMM

True Mono Mode. The TMM bit controls the source of the stereo-to-mono mixer that feeds

into the mono out select mux. If this bit is ‘clear’, the output of the stereo input mixer is sent

to the stereo-to-mono mixer. If this bit is ‘set’, the output of the DAC direct mode mux is sent

to the stereo-to-mono mixer. This allows a true mono mix that includes the PC Beep and

Phone inputs and also works during DAC direct mode.

DAC Direct Mode. The DDM bit controls the source of the line and headphone output drivers.

When this bit is ‘clear’, the CS4202 stereo output mixer drives the line and headphone out-

puts. When this bit is ‘set’, the CS4202 audio DACs (DAC1 and DAC2) directly drive the line

and headphone outputs.

ADC Slot Assignment. The ASA[1:0] bits control the mapping of input slots to the ADC/SRC

block. The default value of ‘00’ selects input slots 3 and 4. See Table 8 on page 30 for all

available Slot Map settings.
