(2) LCD clock control
The LCD clock is determined by the timer LC setting value and
timer LC count source.
After setting data to timer LC, timer LC starts counting by setting
count source with bit 2 of register W4 and setting bit 3 of register
W4 to “1.”
Accordingly, the frequency (F) of the LCD clock is obtained by
the following formula. Numbers ((1) to (3)) shown below the
formula correspond to numbers in Figure 44, respectively.
When using the system clock (STCK) as timer LC count
source (W42=“1”)
F = STCK

(3) LCD RAM
RAM contains areas corresponding to the liquid crystal display.
When “1” is written to this LCD RAM, the display pixel
corresponding to the bit is automatically displayed.
