PAL ID flag. Pahse Alternate Line flag
Output data, timing and clock 3-state output control.
(Default : tied to VDD)
System clock. (Default : 27MHz output. When the EXV port is used
as an input, this can be programmed as an input system clock.)
Pixel rate output clock (Default : 13.5 MHz)
Sliced VBI data output. Data can be from Closed Caption, Teletext,
Intercast, or WSS type encoded data.
When high, this pin indicates that valid VBI data is being clocked out
at the CCDAT pin or at the digital video output.
Multi-purpose I/O portA.
Multi-purpose I/O portB.
Serial clock for IIC host interface. (5V tolerant schmitt trigger pin)
Serial data for IIC host interface.(5V tolerant schmitt triggered open
drain Pins)
Device ID selection for IIC host interface.
