Lock status (HVLK) (configured along with register 0Fh):
0 = Terminal VSYNC/PALI outputs. PAL indicator (PALI) signal and terminal FID/GLCO outputs field ID
(FID) signal (default) (if terminals are configured to output PALI and FID in register 0Fh)
1 = Terminal VSYNC/PALI outputs horizontal lock indicator (HLK) and terminal FID outputs vertical lock
indicator (VLK) (if terminals are configured to output PALI and FID in register 0Fh)
These are additional functionalities that are provided for ease of use.
YUV output enable:
0 = Y(OUT7:0) high impedance (default)
1 = Y(OUT7:0) active
HSYNC, VSYNC/PALI, active video indicator (AVID), and FID/GLCO output enables:
0 = HSYNC, VSYNC/PALI, AVID, and FID/GLCO are high-impedance (default).
1 = HSYNC, VSYNC/PALI, AVID, and FID/GLCO are active.
Vertical blanking on/off:
0 = Vertical blanking (VBLK) off (default)
1 = Vertical blanking (VBLK) on
Clock output enable:
0 = SCLK output is high impedance.
1 = SCLK output is enabled (default).

1 during reset X X
Active after
reset
After reset and before YUV output enable bits are programmed.
TVPOE defaults to 1 and VDPOE is 1.
0 during reset X X
High impedance
after reset
After reset and before YUV output enable bits are programmed.
TVPOE defaults to 0 and VDPOE is 1.
X 0 X High impedance After both YUV output enable bits are programmed.
X X 0 High impedance After both YUV output enable bits are programmed.
X 1 1 Active After both YUV output enable bits are programmed.

Reserved N443_OFF PALN_OFF PALM_OFF Reserved
N443_OFF:
0 = NTSC443 is masked from the autoswitch process. Autoswitch does not switch to NTSC443.
1 = Normal operation (default)
PALN_OFF:
0 = PAL-N is masked from the autoswitch process. Autoswitch does not switch to PAL-N.
1 = Normal operation (default)
PALM_OFF:
0 = PAL-M is masked from the autoswitch process. Autoswitch does not switch to PAL-M.
1 = Normal operation (default)
