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.
Note: This control bit has no effect on the FID/GLCO output when it is programmed to output the
GLCO signal (see bit 3 of address 0Fh). When the GLCO signal is selected, the FID/GLCO output is
always 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 (default)
1 = SCLK output is enabled
Note: To achieve lowest power consumption, outputs placed in the high-impedance state should not be
left floating. A 10-k
Ω pulldown resistor is recommended if not driven externally.
Note: When enabling the outputs, ensure the clock output is not accidently disabled.
