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.
