Wait until 0 to write venab again if in henab or
venab shadow mode.

vtrigger reference
2’bx0: trigger ref = venab
2’b01: last pixel w/ anti-glitch
2’b11: first pixel w/ anti-glitch
Anti-glitch modes work only with venab shadow
mode. First/last pixel must be consistent with
out_seq in this mode.
0x0: no shadow
0x1: simple shadow. When henab_rst_u is
written, henab_set_l, henab_set_u, henab_rst_l
take effect. When venab_rst_u is written,
venab_set_l, venab_set_u, venab_rst_l take
effect.
0x2: henab shadow. Wait for next available blank
period to update positions after henab_rst_u or
venab_rst_u is written.
0x3: venab shadow. Wait for next available vblank
period to update positions after henab_rst_u or
venab_rst_u is written. Venab update takes two
frames. State can be watched in ctrl3[7:5].
