LCD Display RAM
The 7510 group has LCD display RAM apart from user RAM at
addresses 0040
16
to 043F
16
. The LCD display RAM consists of
160 bytes. The memory space for the LCD display RAM can be
selected as zero page addresses 0040
16
to 00DF
16
or third page
addresses 0340
16
to 03DF
16
, by setting the LCD display RAM ad-
dress selection bit.
When the LCD display RAM is at zero page, the addresses 0040
16
to 00DF
16
of user RAM can not be used. When the LCD display
RAM is at third page, the addresses 0340
16
to 03DF
16
of user
RAM can not be used. After reset, the LCD display RAM is set to
third page.
Writing “1” to a bit of the LCD display RAM activates the corre-
sponding pixel on the LCD panel and writing “0” to the bit turns the
pixel off.
Note:
The data of user RAM at the same addresses with the LCD display
RAM (addresses 0040
16
to 00DF
16
or 0340
16
to 03DF
16
) is retained.
Therefore, user RAM can be used effectively by switching the LCD
display RAM address.
