LOCK23 (pin 23) function select
0 = FID (default, if bit 3 is selected to output FID)
1 = Lock indicator (indicates whether the device is locked vertically)
LOCK24B (pin 24) function select
0 = PALI (default, if bit 2 is selected to output PALI)
1 = Lock indicator (indicates whether the device is locked horizontally)
FID/GLCO (pin 23) function select (also see register 03h for enhanced functionality)
0 = FID (default)
1 = GLCO
VSYNC/PALI (pin 24) function select (also see register 03h for enhanced functionality)
0 = VSYNC (default)
1 = PALI
INTREQ/GPCL/VBLK (pin 27) function select
0 = INTREQ (default)
1 = GPCL or VBLK depending on bit 7 of register 03h
SCLK/PCLK (pin 9) function select
0 = SCLK (default)
1 = PCLK (1x pixel clock frequency)
See Figure 3-12 for the relationship between the configuration shared pins.

AVID start pixel MSB [9:2]
Active video cropping start pixel MSB [9:2], set this register first before setting register 12h. The TVP5151
decoder updates the AVID start values only when register 12h is written to. This start pixel value is relative
to the default values of the AVID start pixel.
