Pin No.
5.2.1.2 PCM Interface Registers
The characteristics at the PCM interface (timing, modes of operation, etc. … ) are
programmed in the 4 PCM interface registers and in the Operation Mode Register
OMDR. The function of each bit is described in chapter 5.2.1.3. For addresses, refer to
chapter 4.1.

Function
Transmit PCM interface data: serial data is sent at
standard TTL or CMOS levels (tristate drivers).
These pins can be set to high impedance with a
2 bit resolution.
Tristate control signals for the PCM transmit lines.
These signals are low when the corresponding
TxD# outputs are valid.
Receive PCM interface data: serial data is
received at standard TTL or CMOS levels.
PCM interface frame synchronization signal.
PCM interface data clock, single or double data
rate.
