GAIN_ABCD
ABCD
ABCD_OFST
The input signals A, B, C, D are operated as ABCD = A+B+C+D in the ABCD SUM Amp. The gain is
compensated by Address 03H's GAIN_ABCD from 0dB - +30dB to account for the difference in disc reflectivity
according to disc type. The OFFSET is adjusted by the BACDOFST, then the signal is output as ABCD.
The frequency characteristics of the output AMP are fc = 4MHz when in CD 2x mode, and fc=10MHz in DVD
mode.

This circuit generates the FOCUS OK signal for the SERVO. It consists of a circuit that detects the PEAK of
the ABCD SUM signal, and the circuit that outputs the FOKB signal.
It compares and outputs the ABCD SUM signal's output signal and the comparison LEVEL(FOK_TH).
