The number of pulses in the front dummy LHSYNC (vertical front porch) is specified
by LCDPRVSP<PLV6:0>. This delay time can be set in a range of 0 to 127 pulses of
the LCP0 clock.

The back dummy LHSYNC (vertical back porch) is defined as follows:
(<LVP9:0> + 1) (valid LHSYNC: common size) (front dummy LHSYNC:
<PLV6:0>)
Note: The vertical back porch must be set to “1” or longer in all the cases (STN/TFT).
The enable width of the LLOAD signal is determined depending on the
LCDCTL0<LCP0OC> setting, as shown below.
LCDCTL0<LCP0OC> = 0 : Output at setting value in (LCDDLW) <LDW9:0>
LCDCTL0<LCP0OC> = 1 : Output at valid data
