odd/even field identification output (odd = HIGH)
I
I
horizontal reference for YUV data outputs (for active line 720Y samples long)
set module address input of I
clamping pulse input (digital clamping of external UV signals)
ground 3 (0 V)
port output for general purpose (programmable by subaddress 0D)
fast enable input (active-LOW to control fast switching due to YUV data; HIGH = YUV high-Z
multiplexer control output; source select signal for external ADC (UV signal multiplexing)
fast switch and sync insertion output; gated FS signal from FSI or sync insertion pulse in full screen
RGB mode
ground 4 (0 V)
fast switch input signal fed from SCART/peri-TV connector (indicates fast insertion of RGB signals)
