Before the EEPROM can be programmed, it is necessary to program the desired configuration to the SRAM through the memory control registers. The register data can be written to the SRAM by transferring the active register configuration internally using Method #1, or by direct writes to the SRAM using Method #2.

• Method #1 (Register Commit) requires the active registers be first programmed to the desired configuration, but does not require knowledge of the SRAM/EEPROM map.
• Method #2 (Direct Writes) bypasses any writes to the active registers, allowing the device to continue normal operation without disruption while the SRAM/EEPROM are programmed.

The programming flow for the two methods are different and described as follows.
