Description
ffsc: subcarrier frequency (in multiples of line frequency)
fllc: clock frequency (in multiples of line frequency)
FSC = round ((ffsc/fllc)x2^32)
FSC3 most significant byte
FSC0 least significant byte
NTSC-M: ffsc 227.5, fllc 1716 -> FSC = 21F07C1F
PAL-B/G: ffsc 283.7516, fllc 1728 -> FSC = 2A098ACB
SECAM: ffsc 274.304, fllc 1728 -> FSC = 28A33BB2

Sets horizontal trigger phase related to encoder input.
Values above 1715 (FISE=1) or 1727 (FISE=0) are not allowed.
Increasing HTRIG decreases delay as of all internally generated
timing signals. This register is for the SD path.
Reference mark: analog output horizontal sync (leading slope)
coincides with active edge of RCV used for triggering at
HTRIG=0x398.
Sets horizontal trigger phase related to encoder input.This register
is for the SD path.
Increasing VTRIG decreases delays of all internally generated
timing signals measured in half lines.
Variation range of VTRIG = 0 to 0x1F
0 = Encoder in normal operation mode
1 = Output signal is forced to blanking level. This doesn’t shutdown
the sync and leaves it running.
Selects the phase reset mode of the color subcarrier.
00 = No phase reset or reset via RTC
01 = Phase reset every two lines
10 = Reset every eight fields
11 = Reset every four fields
