EPSON
S1C60N09 TECHNICAL MANUAL
Display memory (40H–6FH or C0H–EFH)
The LCD segments are turned on or off according to this data.
When "1" is written: On
When "0" is written: Off
Reading: Valid for 40H–6FH
Undefined C0H–EFH
By writing data into the display memory allocated to the LCD segment (on the panel), the segment can be
turned on or off. After an initial reset, the contents of the display memory are undefined.
4.6.5 Programming notes
(1) When 40H–6FH is selected for the display memory, the memory data and the display will not match
until the area is initialized (through, for instance, memory clear processing by the CPU). Initialize the
display memory by executing initial processing.
(2) When C0H–EFH is selected for the display memory, that area becomes write-only. Rewriting the
contents with a logical operation instruction (e.g., AND, OR, etc.) which come with read-out opera-
tions is not possible. To perform bit operations, a buffer to hold the display data is required on the
RAM.
