(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.
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.
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."
