FBIAS (focus bias) register addition on.
FIFZC:
This selects the FZC slice level setting command.
When 0, the FZC slice level is determined by the $37 FZSH and FZSL setting values. (default)
When 1, the FZC slice level is determined by the $3F8 FIFZB3 to FIFZB0 and FIFZA3 to
FIFZA0 setting values.
This allows more detailed setting and the addition of hysteresis compared to the $37 FZSH and
FZSL setting.
FPS1, FPS0: Gain setting when transferring data from the focus filter to the PWM block.
TPS1, TPS0: Gain setting when transferring data from the tracking filter to the PWM block.
These are effective for increasing the overall gain in order to widen the servo band, etc.
Operation when FPS1, FPS0 (TPS1, TPS0) = 00 is the same as usual (7-bit shift). However,
6dB, 12dB and 18dB can be selected independently for focus and tracking by setting the
relative gain to 0dB when FPS1, FPS0 (TPS1, TPS0) = 00.

SVDA:
This allows the data set by the $39 command to be output through the audio DAC.
When 0, audio is output. (default)
When 1, the data set by the $39 command is output.
