3.3 M1x66_PCM_IF_CFG_t

Description

PCM interface config structure. This structure contains the PCM interface configuration parameter.

These parameters are usually static and do not change from session to session. The

M1x66_PcmIfConfig API passes the pointer to this structure to configure the PCM interface.
