OPERATION PANEL CONTROLLER
M66271FP
MITSUBISHI <DIGITAL ASSP>
Additional function for LCD module built-in system
As all of the VRAM address in M66271FP are
externally opened for addressing VRAM from MPU
directly.
When consider the LCD module built-in system,connect
pins are increased.
But M66271FP has an additional function for the LCD
module built-in system by lessening connect pins.
Outline of the additional function for the LCD module built-in system
G
Interface pins with MPU
15 kinds of Interface with MPU:A<4:1>,D<7:0>,IOCS,LWR,RD
G
Method of accessing the internal VRAM
Access the internal VRAM through the VRAM address index
register (IDXL,IDXH) and the Data port register (DP) which are
used for I/O register.
The following show the process of accessing VRAM.

Select VRAM address index register (IDXL,
IDXH),and write access address(14bit) as
data.
Select Data port register (DP).
Reading/Writing data for appointed
VRAM address.
Setting to MPUSEL,BHE="L"
G
No use pins set the following.
HWR="H",MCS="H",WAIT= open,MPUCLK="L",MPUSEL="L",
BHE="L",A<0>="L",A<13:5>="L",D<15:8>="L",
G
RESET=Power on reset or soft ware reset
.
(In case of soft ware reset RESET ="H" :set)
G
Enable to change IDXL and IDXH,even if either.
G
Access the DP after writing the mode register (DISP(R1-D2)) =" 0".
Always enable to access (CSES register ="0"),because the display
signal fix "H" or "L" in DISP="0" and a term is no wait access.
G
VRAM address is automatically increased of +1 ,when finished
access to DP.
When access to continuous address,it doesn't need to set IDXL
and IDXH.
