Section 25 LCD Controller
25.3.5
The timing controller register is used to run the controller in a way that matches the display
resolution of the LCD module. The display resolution is set up in the LCDC horizontal number
character number register, LCDC horizontal synchronization signal register, LCDC vertical line
displayed number register, LCDC vertical total line number register, and LCDC vertical
synchronization signal register. The LCD current-alternating period for an STN or DSTN display
is set by using the LCDC ac modulation signal toggle line number register. The initial values in
these registers are typical settings for VGA (640 × 480 dots) on an STN or DSTN display.
The clock to be used is set with the LCD input clock register. The LCD module frame rate is
determined by the display interval + retrace line interval (non-display interval) for one screen set
in a size related register and the frequency of the clock used.
This LCDC has a V
of each vertical retrace line period (to be exact, at the beginning of the line after the last line of the
display). This function is set up by using the LCDC interrupt control register.
25.3.6
An LCD module normally requires a specific sequence for processing to do with the cutoff of the
input power supply. Settings in the LCDC power management mode register, LCDC power supply
sequence period register, and LCDC control register, in conjunction with the LCD power-supply
control pins (VCPWC, VEPWC, and DON), are used to provide processing of power-supply
control sequences that suits the requirements of the LCD module.
Figures 25.4 to 25.7 are summary timing charts for power-supply control sequences and table 25.5
is a summary of available power-supply control sequence periods.
