Description

ROUT1

PCM data output pin. Output signal changes depending on the setting of

the IOM pins (refer to the block diagram).

Data is always output on the rising edge of SCK. This pin becomes high

impedance while there is no data or during reset.

In 2-channel parallel I/O mode, this pin becomes ROUT for channel 1 and

outputs the PCM signal synchronous with SYNC1. In 2-channel serial I/O

mode, this pin outputs the ROUT signal as a multiplexed PCM signal of ROUT

signals for channel 1 and channel 2 synchronous with SYNC1.

In 1-channel cross-connected mode, this pin becomes the cross-connected

ROUT pin for channel 1, and outputs the PCM signal synchronous with SYNC1.

RIN1

PCM data input pin. Pin use changes depending on the setting of the IOM

pins (refer to the block diagram).

In 2-channel parallel I/O mode, this pin becomes RIN for channel 1 and

inputs the PCM signal synchronous with SYNC1. In 2-channel serial I/O

mode, this pin sequentially inputs RIN as a multiplexed PCM signal from

channel 1 and channel 2 synchronous with SYNC1. In 1-channel cross-

connected mode, this pin is not used, and should be fixed at "L".

Data is captured on the falling edge of SCK.

SIN1

PCM data input pin. Pin use changes depending on the setting of the IOM

pins (refer to the block diagram).

In 2-channel parallel I/O mode, this pin becomes SIN for channel 1 and

inputs the PCM signal synchronous with SYNC1. In 2-channel serial I/O

mode, this pin sequentially inputs SIN as a multiplexed PCM signal from

channel 1 and channel 2 synchronous with SYNC1. In 1-channel cross-

connected mode, this pin becomes the cross-connected SIN pin for channel

1, and inputs the PCM signal synchronous with SYNC1.

Data is captured on the falling edge of SCK.
