(1) The internal signal is generated when LAT inputs GS data when the display timing reset bit (TMGRST) is set to '1'. This signal has the
same function as BLANK = 1. Furthermore, the signal is generated at the 4096th GSCLK when the auto display repeat bit (DSPRPT) is set to
'1'.
(2) When auto display repeat is on.
