8 bit capacity
Vertical sync processing by scale control
Non-scaled mode to get full picture or to gate videotext
lines
UV input and output data binary/two’s complement
Switchable RGB matrix and anti-gamma ROMs
16-word FIFO register for 32-bit output data
Output formats: 5-bit and 8-bit RGB, 8-bit YUV or 8-bit
