Power pin for delay RAM
Ground pin for delay RAM
Program SYNC signal input pin
LR clock pin for serial data input (DIN)/serial data output (DOUT).
When you carry out a slave operation to a serial input/output data, please set it as an input.
And when you carry out a master operation, please set it as an output (command 43h: SIOS).
Output frequency can perform selection of 1 fs/2 fs by ELRQS (command: 40h).
Bit clock pin for serial data input (DIN)/serial data output (DOUT).
When you carry out a slave operation to a serial input/output data, please set it as an input.
And when you carry out a master operation, please set it as an output (command 43h: SIOS).
Output frequency can be select as follows by EBCQS (command: 40h).
Serial data input pin. The serial data of a total of 6-channels can be inputted. Switching of the
number of channel is set by CHSI (command: 42h). Moreover, switching of master/slave
function is set by SIS (command: 42h)
Serial data output pin. Connected to internal register for output in DSP block.
The internal register connected is set up by CHSO (command: 43h).
