Bit[4]: PCM Clock On
•
0 = PCM clock is terminated after last data bit has been
transmitted
•
1 = make PCM clock available continuously
Bit[3]: Reserved
Bit[2]: PCM Sync Source
•
0 = PCM sync page generated from system clock
•
1 = PCM sync page generated from frame clock
Bit[1]: Master/Slave
•
0 = PCM I/F slave, external PCM clock and synchronization
•
1 = PCM I/F master, internal PCM clock and synchronization
Bit[0]: PCM Direction
•
0 = port A receive, port B transmit
