EEPROM Setting Following

The ST7632 chip provides the Write and Read function to write the Electronic Control value and Built-in resistance ratio

into and read them from the built-in EEPROM. Using the Write and Read functions, you can store these values appropriate

to each LCP panel. This function is very convenient for user in setting from some different panel

’s voltage. But using this

function must attention the setting procedure. Please see the following diagram.

Note: When writing value to EEPROM, the voltage of Voutin must be more than 16V.

Referential Instruction Setup Flow: Initializing with the built-in Power Supply Circuits
