Sync generator
The sync generator is the timing master of the encoder. It generates all the signals
required to control the signal processing, provide the composite sync signal, insert
the color burst, etc. Via the FISE control bit (register STDCTL, offset 0x61), the circuit
can be set to generate 50 Hz patterns for e.g., PAL B or 60 Hz patterns (NTSC M). It
is possible to modify the number of lines per field by ±0.5 lines to generate a
non-interlaced output signal. The sync generator also provides HS (Horizontal Sync),
VS (Vertical Sync) and O_E (Odd/Even) signals to control the rest of the encoder.
