S1D13700 Technical Manual
Example of display memory mapping by the S1D13700
(1)Character code table
(2)Graphic data table
(3)CG RAM table (for external characters)
To make the most of the above-mentioned functions of the S1D13700, a high-speed interfacing
method is used to enable pipelined command processing between the MPU and S1D13700. Most
commands of the S1D13700 are processed so that the controller completes the processing of any
input command before the next command is issued from the MPU. Therefore, the MPU does not
need to frequently check the status of the S1D13700, and is not kept waiting by the S1D13700.
Thus, the high-speed interfacing method adopted for the S1D13700 helps minimize possible
reduction in the MPU’s processing capability.
Moreover, the MPU can access the above display space at any time irrespective of display mode
(except in sleep mode).
(4)CG ROM table
• A memory area to store character code when displaying text
• 1 character = 8 bits
• Variable table mapping (by altering the scroll start address)
• A memory area to store bitmap data
• 1 word = 8 bits
• Variable table mapping
• A character generator whose character patterns can be altered by the MPU as desired
• Maximum 8 x 16 bits (16 bytes per character)
• Maximum 64 discrete characters, or 256 characters when not using CGROM
• Internal CG RAM used
• Variable table mapping
• Maximum 5 x 7 bits
• Maximum 160 characters
• Mapped to addresses 8030h–85AFh. Data cannot be read out by the MPU.
