Note 1: In the case of 80 series CPU, access to MSM6262-xx is done by WR and RD. So, a bit for part of the read/write code is not required.
Clears all of the display. and sets
address 0 of DD RAM in the address
counter.
CR/C = L: Cursor home
CR/C = H: Carriage Return
UL = H: Writes the underline in the
cursor part before executing
this instruction.
UL = L : Erases the underline in the
cursor part before executing
this instruction.
Sets whether the display of the direction of
cursor (I/D) move should be shifted or not.
When the data is being written or read,
this operation is performed.
This instruction also sets whether the
character code of DD RAM is used as
CG ROM or CG RAM.(A/O)
Shifts the cursor and display without
changing the DD RAM contents.
(S/C, UD/RL,UR/DL)
The line to be displayed in the uppermost
position can be set.
Sets the CG RAM address.
The dara, which will be sent/received
after the CG RAM address is set, is
CG RAM data.

Sets the following:
No. of display digits (N), Character font

Sets the following:
All display on/off (D), Cursor display
on/off (C), Character on the cursor
position blink on/off (B), Underline display
on/off (UC), Character, on the
underline, blink on/off (UB)
Writes a data in either DD RAM or
CG RAM.
Sets DD RAM address.
The data which is sent/received after
that is DD RAM data.
Reads following data:
Data on the underline, DD RAM or
CG from RAM data.
Reads the data either from DD RAM
or from CG RAM.
Reads the address counter contents.
Busy 1 flag (B1F) shows that
MSM6262-xx's internal operation is going on.
Busy 2 flag (B2F) shows that the revising
of display starting line is going on.
CG/DD shows whether the data, being
transmitted or received, is of CG RAM
or DD RAM.
I/D shows the direction in which cursor moves.
S shows the display shift.
A/O shows that the DD RAM character
code is CG RAM character code or
CG RAM character code.
D shows the all display on/off.
UD shows underline display on/off.
