LCD Display RAM
Address 004016 to 004F16 is the designated RAM for the LCD dis-
play. When “1” are written to these addresses, the corresponding seg-
ments of the LCD display panel are turned on.
LCD Drive Timing
The LCDCK timing frequency (LCD drive timing) is generated inter-
nally and the frame frequency can be determined with the following
equation;
(frequency of count source for LCDCK)
(divider division ratio for LCD)
f(LCDCK)=
f(LCDCK)
duty ratio
Frame frequency=
