I (SEL=High: CS I/F)
In AUTO READ operation and ECL operation, the address of
EEPROM is selected by the EA0 and the EA1 pins.
(SEL=Low: LD I/F)
The address of EEPROM is selected by the EA0 and the EA1
pins.
I When the ECL pin receives high pulse, the data in EEPROM is
automatically loaded to each corresponding D/A, starting from
AO1 to AO12 in order. Then each D/A output is settled to
pre-determined value.
I Input Data Format Select Pin
SEL=High : CS I/F
SEL=Low : LD I/F
After power-up, this pin should be kept either at "high" or "Low."
