PAW3203DI
Wireless Optical Mouse Single Chip
6. EEPROM Table
1. After power on, PAW3203DI will check EEPROM, if EEPROM address = 0x01 and data = 0xAA, continue
to read EEPROM address 0x02.
2. When reading successive data is zero, PAW3203DI stops to read data from EEPROM.
3. Placing updated address and data continuously.
