START_FO[3:0] , Addr 44 (CP), Address 0x80[3:0]
A control to shift the position of the start of odd field edge of the FIELD signal output by the CP core.
This register stores a signed value in a twos complement format. START_FO[3:0] the number of lines by which the start of the odd fields
edge of the FIELD signal is shifted (for example, 0x0D corresponds to a shift of 3 lines toward the active video, 0x05 corresponds to a shift
of 5 line away from the active video).
Function
START_FO[3:0] Description
0x0 (default) Default value.
0x0 to 0x7 The edge of the FIELD signal corresponding to the start of the odd field is shifted toward the active video.
0x8 to 0xF The trailing of the FIELD signal corresponding to the start of the odd field is shifted away from the active video.
