DESCRIPTION
The M35071-XXXSP/FP is a character pattern display control IC can
display on the CRT display the liquid crystal display and the plasma
display. It can display 2 pages (24 characters
12 lines per 1 page)
at the same time. It uses a silicon gate CMOS process and it housed
in a 20-pin shrink DIP package (M35071-XXXSP) or a 20-pin shrink
SOP package (M35071-XXXFP).
For M35071-002SP/FP that is a standard ROM version of M35071-
XXXSP/FP respectively, the character pattern is also mentioned.

are assigned to the display RAM, address
120
16
to 128

are assigned to the display control registers. The in-
ternal circuit is reset and all display control registers (address 120
16

to 128
16
) are set to "0" when the AC pin level is "L". And then, RAM
is not erased and be undefinited. This memory is consisted of 2

pages : page 0 memory and page 1 memory (their addresses are
common), page controlled by DAF bit of each address when writing
data. For detail, see "Data input". Memory constitution is shown in
Figure 1 and 2.

Note: Page 0 and page 1 registers are found in their respective pages. For example, HP10 to HP0 of the page 0 memory sets the horizontal
display start position of page 0, whereas HP10 to HP0 (same register name) of the page 1 memory sets the horizontal display start
position of page 1. Also, registers common to both page 0 and page 1 are found only in the page 0 memory. For example, PTC0 is the
control register of the P0 pin and is found only in the page 0 memory.
