Address 004016 to 004F16 is the designated RAM for the LCD dis-
play. When “1” are written to these addresses, the corresponding
segments of the LCD display panel are turned on.

LCD Drive Timing
The LCDCK timing frequency (LCD drive timing) is generated in-
ternally and the frame frequency can be determined with the
following equation;
f(LCDCK) =
Frame frequency =
(frequency of count source for LCDCK)
(divider division ratio for LCD)
f(LCDCK)
(duty ratio)

the LCD mode register) to “0” and the LCD panel turns off.To
make the LCD panel turn on after returning from the stop mode,
set the LCD enable bit to “1”.
