Bit swap Ancillary Enable Parity modifier SAV/EAV modifier Output mode
Output mode:
000 = Mode 0 : Unscaled data clocked by clock 1
001 = Mode 1 : Scaled data clocked by clock 1
010 = Mode 2 : Multiplexed data with separate clocks
011 = Mode 3 : Multiplexed data with clock 1 at 54 MHz
100 = Mode 4 : Unscaled/scaled field toggled data clocked by clock 1
SAV/EAV modifier:
0 = SAV/EAV codes not modified
1 = SAV/EAV MSB modified. MSB = 1 indicates unscaled data, MSB = 0 indicates scaled data
Parity modifier:
0 = Parity calculation includes SAV/EAV MSB.
1 = Parity calculation does not include SAV/EAV MSB.
Ancillary enable:
0 = Ancillary data not enabled
1 = Ancillary data packet added to indicate scaled or unscaled data
Note : Scaled/unscaled ancillary data cannot be enabled at the same time as VBI ancillary data
Bit swap:
0 = chx_out(0) corresponds to data LSB, chx_out(7) corresponds to data MSB
1 = chx_out(0) corresponds to data MSB, chx_out(7) corresponds to data LSB
