EEPROM Access
Customer can select ADM6996F read EEPROM contents as chip setting or not.
ADM6996F will check the signature of
EEPROM to decide read content of EEPROM or not.
RESETL & EEPROM content relationship
Keep at least 30ms after RESETL from 0Æ1. ADM6996F will read data from EEPROM.
After RESETL if CPU update EEPROM that ADM6996F will update configuration
registers too.
When CPU programming EEPROM & ADM6996F, ADM6996F recognizes the
EEPROM WRITE instruction only. If there is any Protection instruction before or after
the EEPROM WRITE instruction, CPU needs to generate separated CS signal cycle for
each Protection & WRITE instruction.
CPU can directly program ADM6996F after 30ms of Reset signal rising edge with or
without EEPROM
