Note 1: The "75 Hz-2" Drive Sequence type signals and WB Adjustment Table 4 are output only
when "75 Hz-2" (VFQS07) is selected for internal signals (mask signals).
When external signals are selected and the Drive Sequence type is 75 Hz, "75 Hz-1" is
output because "75 Hz-1" and "75 Hz-2" are not distinguished for external signals.
