I/O

CMOS I/O

Input:

All data in the EEPROM are erased if the

LEARN(LED) pin turns low and the CLEAR(CS) pin

turns high over 1 seconds, or if the CLEAR(CS) pin

turns high for over 1 seconds in the learning state.

Output: EEPROM chip selection signal output

(connected to the CS pin of EEPROM)
