FBKGC - Define the output configuration for FBKG pin. When it is set to "0", the FBKG outputs during the dis-
playing of characters or windows, otherwise, it outputs only during the displaying of characters.

TEST - = 0
=1
Normal mode.
Test mode, not allowed in applications.
FBKGP - Select the polarity of the output pin FBKG
=1
Positive polarity FBKG output is selected.
=0
Negative polarity FBKG output is selected.
The initial value is 1 after power up.
PWMCK - Select the output options to HTONE/PWMCK pin.
=0
HTONE option is selected.
=1
PWMCK option is selected with 50/50 duty cycle and synchronous with the input HFLB.
The frequency is selected by (VCO1, VCO0) shown as Table 4 on page 12.
The initial value is 0 after power up.
SELVCL - Enable auto detection for horizontal and vertical syncs input edge distorition while the bit is set to
"1". The initial value is 0 after power up.
HSP - = 1 Accept positive polarity Hsync input.
= 0 Accept negative polarity Hsync input.
VSP -
= 1 Accept positive polarity Vsync input.
= 0 Accept negative polarity Vsync input.
VCO1, VCO0 - Select the appropriate curve partitions of VCO frequency to voltage based on HFLB input and
horizontal resolution register (HORR).
