ELRI/O
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).

EBCI/O
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).
