2.14.4 M1x66_SelectSampleRate
Description
Select PCM sample rate. The 73M1x66B device can operate in one of two sample rates – 8 kHz or
16 kHz sample rate. The device defaults to 8 kHz operation upon startup and can be changed to run at
16 kHz using this API.
Notes: Changing the PCM sample rate will affect the following:
1. Data presented in PCM timeslots – reallocation of transmit and receive timeslots may be necessary
or required to properly communicate with peer interface.
2. Barrier interface operation – a momentary loss of synchronization on the barrier interface is expected.
However, the driver will automatically attempt to recover barrier synchronization. The SYNC lost
event is sent and should be followed by SYNC restored event when the barrier is synced up again.
