Terminal GPCL function select:
00 =
Terminal GPCL is logic 0 output (default)
01 =
Terminal GPCL is logic 1 output
10 =
Terminal GPCL is vertical blank output
11 =
Terminal GPCL is external sync lock control input
When GPCL is configured as a vertical blank output, the vertical blanking on/off bit is used to activate the
output.
When GPCL is configured as a sync lock control, it can be used to force the internal PLLs to their normal
settings. This causes all clocks and synchronization signals to assume nominal values. The sync lock
control input is active high.
Terminals PALI and FID function select:
0 =
Terminal PALI outputs PAL indicator signal and terminal FID outputs field ID signal (default)
1 =
Terminal PALI outputs horizontal lock indicator (HLK) and terminal FID outputs vertical lock
indicator (VLK)
YUV output enable:
0 =
YUV high impedance (default)
1 =
YUV active
Y[7:0] and UV[7:0] terminals are controlled by this bit, the YUV enable bit in register C2, and the OEB
terminal.
