Both PCM modes are discussed in this section, followed by additional PCM topics.
3.19.1 Auxiliary PCM
The auxiliary PCM interface enables communication with an external codec to support
hands-free applications.
υ
-law codec are supported by the auxiliary PCM interface.
The auxiliary codec port operates with standard long-sync timing and a 128 kHz clock. The
AUX_PCM_SYNC runs at 8 kHz with 50% duty cycle. Most
υ
-law codec support the 128
kHz clock.
