Headphone Power Control
Configures how the SPKR/HP pin, 31, controls the power for the headphone amplifier.
Speaker Power Control
Configures how the SPKR/HP pin, 31, controls the power for the speaker amplifier.
Auto-Detect
Configures the auto-detect circuitry for detecting the speed mode of the CODEC when operating as a
slave.
Notes:
1. The SPEED[1:0] bits are ignored and speed is determined by the MCLK/LRCK ratio.
2. When AUTO is disabled and the CODEC operates in master mode, the MCLKDIV2 bit is ignored.
3. Certain sample and MCLK frequencies require setting the SPEED[1:0] bits, the 32k_GROUP bit
