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.
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.
block. The default value of ‘00’ selects input slots 3 and 4. See Table 8 on page 30 for all
available Slot Map settings.
True Mono Mode. The TMM bit controls the source of the stereo-to-mono mixer that feeds
DAC Direct Mode. The DDM bit controls the source of the line and headphone output drivers.
ADC Slot Assignment. The ASA[1:0] bits control the mapping of input slots to the ADC/SRC
