There are two other parameters to configure in this module, the HOZVAL and the LINEVAL fields of the
LCDFRMCFG:
 HOZVAL configures the number of active LCDDOTCK cycles in each line. The number of active cycles in
each line is equal to (HOZVAL+1) cycles. The minimum value of this parameter is 1.
 LINEVAL configures the number of active lines per frame. This number is equal to (LINEVAL+1) lines. The
minimum value of this parameter is 1.
Figure 37-3, Figure 37-4 and Figure 37-5 show the timing of LCDDOTCK, LCDDEN, LCDHSYNC and LCDVSYNC
