Panel Interface Control 5 (R014h)
PCDIVH[2:0], PCDIVL[2:0]: When DM=1 and RGB I/F is selected, display operation is executed using
DOTCLKD. PCDIVH and PCDIVL define division ratio of DOTCLK to generate DOTCLKD.
PCDIVH is used to define number of DOTCLK in High period in units of one clock.
PCDIVL is used to define number of DOTCLK in Low period in units of one clock.
Make sure that PCDIVL=PCDIVH or PCDIVH-1.
Write PCDIVH and PCDIVL values so that DOTCLKD frequency is the closest to internal oscillation
clock frequency 678KHz.
For details, see “Setting Example of Display Control Clock in RGB Interface Operation”.
