• Determining serial set data VOFD0—3
(1) Provisional setting
Serial data VOFD0—3 settings are made according to the value of V_OFCCD as shown in table 4.
(2) Actual setting
The set data is adjusted so that the CLP pin (pin 23) voltage is closest to 1/2 AV_DD when AGC gain
is set to the maximum.
The data obtained in (2) is used as the serial set data.
