Function Descriptions
Example
The following C program shows the uses of the EEPROM functions for the Lite0 device.
Program Description:
This program writes 5 data bytes in EEPROM memory from one user buffer, Temp1. Then
data bytes are read from the same EEPROM memory and stored in another buffer, Temp2.
The written data and data read from the two buffers are then compared.
