6. Functions Description
6-1 Functional Definition
‹ After power on, it is necessary to reset. The RST is kept Low between 5 clocks up (oscillation
clock).
‹ When HALT = Low, the oscillation stops. The power supply for the LCD must be turned off, to
protect the LCD from DC bias.
‹ The HALT function( HALT = Low) includes the RESET function( RST =Low).
‹ The column/line counter and display register are cleared by RST . (Other registers are not cleared.)
Disable the display using the clear-display register
‹ The status must be checked before data or commands are sent. The MSB=0 status check must be
done in particular. There is a possibility of erroneous operation due to a hard interrupt.
‹ STA0 and STA1 must be checked at the same time. When a command is executed, data
transmission errors may occur.
‹ The RA6963 can only handle one byte per machine cycle (16 clocks). It is impossible to send more
than two data in a machine cycle.
‹ When using a command with operand data, it important to send the data first, and then executes the
command.
‹ The character fonts used by the RA6963 are different from ASCII codes.

6-4 RAM Interface
The external RAM is used to store display data (text, graphic and external CG data).
With single-scan, text data, graphic data and external CG data can be freely allocated to the memory
area (64 KB max).
With dual-scan, LCD-I is allocated to 0000h to 7FFFh (32 KB max), LCD-II is allocated to 8000h to
FFFFh (32-KB Max). Text data, graphic data and external CG data can be freely allocated in LCD-I. In
LCD-II, the same addresses must be allocated as in LCD-I, except A15. A15 determines selection of
LCD-I or LCD-II.
It can be used the address-decoded signals CE0 (0000h to 07FFh), CE1 (0800h to 0FFFh) within 4
KB. CE0 and CE1 allow decoding of addresses in the ranges (0000h to 07FFh) and (0800h to 0FFFh)
respectively within a 4-KB memory space.

Note 4: When using the MSB=0 command, a Status Read must be performed.
If a status check is not carried out, the RA6963 cannot operate normally, even after a
delay time.
The hardware interrupt occurs during the address calculation period (at the end of each
line).
If a MSB=0 command is sent to the RA6963 during this period, the RA6963 enters Wait
status.
If a status check is not carried out in this state before the next command is sent, there is
the possibility that command or data will not be received.

RA6963 assign External character generator, when character code set 80h to FFh in using Internal
character generator. Character code 00h to 80h assign External character generator, when
External generator mode.
The senior five bits define the start address in external memory of the CG RAM area. The next
eight bits represent the character code of the character. In internal CG ROM mode, character
Codes 00h to 7Fh represent the predefined “internal” CG ROM characters, and codes 80h to FFh
Represent the user’s own “external” characters. In external CG RAM mode, all 256 codes from 00h
to FFh can be used to represent the user’s own characters. The three least significant bits indicate
one of the eight rows of eight dots that define the character’s shape.

The display mode is defined by this command. The display mode does not change until the next
command is sent. The logical OR, EXOR, AND of text or graphic display can be displayed.
In internal Character Generator mode, character codes 00h to 7Fh are assigned to the built-in
Character generator ROM. The character codes 80h to FFh are automatically assigned to the external
character generator RAM.

Note: Attribute functions can only be applied to text display, since the attribute data is placed in the

Attribute Function
The attribute operations are Reverse display, Character blink, bold and Inhibit. The attribute data is
written into the graphic area, which was defined by the Set Control word command. Only text display is
possible in Attribute Function mode; graphic display is automatically disabled. However, the Display
Mode command must be used to turn both Text and Graphic on that in order to for the Attribute
function available.
The attribute data for each character in the text area is written to the same address in the graphic area.
The Attribute function is defined as follows.

This command is convenient for sending a full screen of data from the external display RAM. After
Setting Auto mode, a Data Write (or Read) command does not need sent between each datum. A Data
Auto Write (or Read) command must be sent after a Set Address Pointer command. After this
Command, the address pointer is automatically incremented by 1 after each datum. In Auto mode, the
RA6963 cannot accept any other commands.
The Auto Reset command must be sent to the RA6963 after all data has been sent, to clear Auto
Mode.
Note: A Status Check for Auto Mode
STA2, STA3 should be checked between sending of each datum. Auto Reset should be
performed after checking STA3=1 (STA2=1). Refer to the following flowchart.

9-4 Application Block Diagram
All LCD require two power sources, VDD for logic circuits and VEE for Liquid Crystal (LC) drive. Some
graphics LCD modules will run directly of a single VDD supply by generating the VEE voltage on-board;
others will require an external DC-DC converter to generate the negative VEE voltage. Refer to
individual specifications for details.
