Function
This bit indicates the state of the EEPROM program memory
1 = EEPROM is not in a programming cycle
0 = EEPROM is in a programming cycle

Power-Down selection bits
When the DAC is powered down, most of the internal circuits are powered off and the op amp is
disconnected from the V
00 = Not Powered Down (Normal operation)
01 = Powered Down - V
10 = Powered Down - V
11 = Powered Down - V
