The on-chip EEPROM is a non-volatile memory array used to permanently store register data for a custom device start-up configuration setting to initialize registers upon power up or POR. The EEPROM is comprised of bits shown in the EEPROM Map. The transfer must first happen to the SRAM and then to the EEPROM. During EEPROM write, R49[2] is a 1 and the EEPROM contents cannot be accessed. The following details the programming sequence to transfer the entire contents of SRAM to EEPROM.

1. Make sure the Write SRAM procedure (Write SRAM) was done to commit the register settings to the SRAM with start-up configurations intended for programming to the EEPROM.
2. Write 0xBE to R56. This provides basic protection from inadvertent programming of EEPROM.
3. Write a 1 to R49[0]. This programs the entire SRAM contents to EEPROM. Once completed, the contents in R48 will increment by 1. R48 contains the total number of EEPROM programming cycles that are successfully completed.
4. Write 0x00 to R56 to protect against inadvertent programming of EEPROM.
