the status register which then allows accesses to the Non-

Volatile Memory map.

Write-Through Cycles

During startup and local register loading, any incoming

writecycles to the Non-Volatile Memory will be held off until

start up and configuration is complete. During normal

operation, writes to the Non-Volatile Memory shall be

extended until such time that the data is both written to and

read back from the external EEPROM.
