Row 15, Column 15:
OSD_EN — OSD Enable
HPOL — Horizontal Sync Polarity
VPOL — Vertical Sync Polarity

Set this bit to enable the OSD module output pins, OSDR, OSDG,
OSDB, and FBKG. When OSD_EN is clear, all OSD output pins are
high impedance. This bit is cleared after a POR, reset, or when
OSDRST bit (bit-5 in OSD control register) is set.
This bit selects the polarity of the incoming horizontal sync signal on
PHSYNC pin. If sync signal is negative polarity, clear this bit. If sync
signal is positive polarity, set this bit. This bit is cleared after a POR,
reset, or when OSDRST bit is set.
This bit selects the polarity of the incoming vertical sync signal on
PVSYNC pin. If sync signal is negative polarity, clear this bit. If sync
signal is positive polarity, set this bit. This bit is cleared after a POR,
reset, or when OSDRST bit is set.
1 = OSD output pins: OSDR, OSDG, OSDB, FBKG enabled
0 = OSD output pins held at high impedance
1 = Set for positive horizontal sync signal
0 = Clear for negative horizontal sync
1 = Set for positive vertical sync signal
0 = Clear for negative vertical sync
