When ADCR and ADCL are used together as a
stereo pair, then both ADCs must be enabled
together using a single register write to Register R11
(0Bh).
Left ADC enable
0 = disabled
1 = enabled
When ADCR and ADCL are used together as a
stereo pair, then both ADCs must be enabled
together using a single register write to Register R11
(0Bh).
Master codec enable bit. Until this bit is set, all codec
registers are held in reset.
0 = All codec registers held in reset
1 = Codec registers operate normally.
Reset by state machine.
