Output serial data the trailing edge of SCK . When the n-numbe r

0of pPD63000s are connected in series, this can be connected t o the SI of the following stage .

This input can turn off all indicator or displays, and can dim the m by applying a random duty pulse from outside . Active low .

Transmits the connects of the serial shift register to the buffe r

Iregister at low level, to latch the connects at the rising time . Active rising (leading) edge .

This is the data input pin . Inputs data to the shift register at th e

I

rising edge of SCK .

Reads out the SI data to the shift register at the rising edge o f

ISCK .

Outputs data from SO at the trailing edge of SCK .

When CS is high, this inhibits SCK and LH, and when CS is low , activates SCK and LH .

Connect to the GND terminal of the system .
