Data Sheet
PDC
PFS
PFS
In PCM Master mode (PFS and PDC are in output mode) PFS rises with a rising edge of PDC, and it’s designed
to be sampled with the falling edge of PDC at any (slave) chip connected to the PCM interface. The first PDC
cycle in which PFS is sampled as logic-1 after a sampling of logic-0, is considered as the first cycle of the new
PCM frame.
