RECORD SELECTOR
w
Table 10 ADC Slot Mapping
The record selector determines which input signals are routed into the audio ADC. The left and right
channels can be selected independently. This is useful for recording a phone call: one channel can
be used for the RX signal and the other for the TX signal, so that both sides of the conversation are
digitized.

0 :No boost
Note: RECBST gain is in addition to the
microphone pre-amps (MPABST and
MPBBST bits) and record gain (GRL and
GRR / GRL bits).
