EEPROM Controller Busy (EPC_BUSY)
When a 1 is written into this bit, the operation specified in the
EPC_COMMAND field of this register is performed at the specified
EEPROM address. This bit will remain set until the selected operation is
complete. In the case of a read, this indicates that the Host can read valid
data from the
E2P_DATA registers should not be modified until this bit is cleared. In the
case where a write is attempted and an EEPROM is not present, the
EPC_BUSY bit remains set until the
