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.
