Clock Output Frequency. Programmable clock output on PCLK O pin is determined using the following formula
PCLK O = 256
×
PCR/2
COF
where COF = 0:11 and PCR is the value of the Programmable Clock Rate Register,
SS [38]. If COF > 11, then PCLK O is disabled.
Capture not equal to Playback.
0 = Capture equals Playback. T he capture sample rate is determined by the playback sample rate in SS [02].
1 = Capture not equal to Playback.
CD Enable, Set to “1” when a CD player is connected to I

S (0), maps SoundBlaster CD mixer controls from
the analog CD attenuator inputs to I

S (0) serial port.
Sound System Enable.
0 = SoundBlaster Mode.
1 = Sound System Mode under Windows.
Note: When in SoundBlaster Mode, the Codec ADC and DAC channels will be used solely for converting
SoundBlaster data.
