A0/CSB

I2C interface device address data input pin for I2C interface

Chip Select pin for SPI 3-wire Interface

SCL/CLK

Serial clock input pin

Serial Clock (SCL) Input for I2C interface

Serial Clock (CLK) Input for SPI 3-wire Interface

SDA/DIO

I/O

Serial data input/output pin. Data is input to or comes out from the shift register at the

clock rising edge.

I2C interface serial data (SDA) Input/Output – NMOS open-drain output.

SPI 3-wire serial interface serial data input/output – CMOS output.

OSC

I/O

System OSC Input / output pin.

If the IRC Mode command is programmed, the system clock is sourced from the internal

RC oscillator and the system clock is output on the OSC pin.

If the Slave Mode or ERC Mode command is programmed, the system clock is sourced

from an external clock on the OSC pin.

SYNC

I/O

If the MASTER MODE command is programmed, the synchronous signal is output on

the SYNC pin.

If the SLAVE MODE command is programmed, the synchronous signal is input on the

SYNC pin.

R_EXT

External resistor connection input.

Connected to an external resistor to setup the output port current level.

COM0~COM7

LED common output pins.

ROW0~ROW27

LED row output pins.
