CODING

CODE1, CODE2 and CODE3 are internally pulled up to Vcc by pull-up resistors.

To encode each code bit to “1”:

Open the corresponding CODE pin, or Insert a capacitor between CODE pin and Vss.

To encode each Code bit to “0”:

Connect the corresponding CODE pin to Vss.

EXPLANATION OF OUTPUT TYPES: SP, HP AND CP

SINGLE PULSE (SP1~SP10)

If there is no error in the receiving signal of the 12-bit data check, it will generate a single pulse output.
