HD404849 Series

LCD Controller/Driver

The MCU has an LCD controller and driver which drive 4 common signal pins and 32 segment pins. The

controller consists of a RAM area in which display data is stored, a display control register (LCR: $01B),

and a duty-cycle/clock-control register (LMR: $01C) (figure 84).

Four duty cycles and the LCD clock are programmable, and a built-in dual-port RAM ensures that display

data can be automatically transmitted to the segment signal pins without program intervention. If a 32-kHz

oscillation clock is selected as the LCD clock source, the LCD can even be used in watch mode, in which

the system clock stops.
