When LCDCTL0<FRMON>=1 and LCDCTL0<DLS>=1, frame output is inverted at
intervals set in LCDDVM0<FML3:0> and the LFR signal is inverted at intervals of
"LCP0 × M". The "M" value is specified in LCDDVM0<FMP7:4>.
When <DLS>="1" LFR signal synchronous with front edge of LHSYNC signal.
So, prohibit to set <FREDGE>=1, always need to set <FREDGE>=0.
