CLMPEN
Clamping pulse output (CLAMP) enable
. If CLMPEN = 1, pin
PWM8/CLAMP/P3.0 is switched to the CLAMP output. If CLMPEN = 0,
the CLAMP function is disabled. The CLAMP function always overrides
other alternative functions such as PWM8 and P3.0.
Basic display patterns selection
. If PATTYP = 0, the white display
pattern is selected. If PATTYP = 1, the cross hatch display pattern is
selected.
Vertical pulse output modes selection
. If VPG = 0, a free running
vertical sync pulse signal is selected. If VPG = 1, a vertical substitution
pulse signal is selected.
Vertical output pulse polarity selection
. If PVSI = 0, the positive
polarity is selected. If PVSI = 1, the negative polarity is selected.
Horizontal pulse output modes selection
; see Table 61.
The clamp pulse at the back porch or at the front porch selection
.
This bit is only valid when CLMPEN is set HIGH. If FBPO = 1, the
horizontal back porch clamp pulse is selected. If FBPO = 0, the
horizontal front porch clamp pulse is selected.
Polarity of the horizontal and clamping output pulse indication.
If PHSI = 0, the positive polarity is selected. If PHSI = 1, the negative
polarity is selected.
