connected to ground (shift pin for testing)
connected to ground (action pin for testing)
reset, active-LOW
clock reference, sync from external to ensure in-phase signals on the Y-, CUV- and YUV-bus
ground 1 (0 V)
status bit output FSST0 or port 1 output for general purpose (programmable by subaddress 0C)
status bit output FSST1 or port 2 output for general purpose (programmable by subaddress 0C)
black level clamp pulse output (begin and stop programmable), e.g. for TDA8708A (ADC)
line-locked system clock input signal (27 MHz)
