FUNCTIONAL DESCRIPTION
General Description of Block Diagram
1. Address Pointer
An address pointer is a 5-bit counter which assigns the write destination or read destination
address of CGA RAM and AB RAM, and the write destination address of CHB RAM and ABB
RAM. The value of the address pointer can be set by the LPA command. The value of the
address pointer is automatically incremented by 1 after executing the AINC and CHB
commands, or after transferring input display data.
2. Character Generator Address RAM (CGA RAM)
The character generator address RAM stores 8-bit character codes of the character generator
ROM. A maximum of thirteen 8-bit character codes can be stored.
3. Arbitrator RAM (AB RAM)
The arbitrator RAM stores the lighting data of the arbitrator. Lighting data is stored in 5 dot
units, and a maximum of 65 dots of lighting data can be stored.
4. Character Blink RAM (CHB RAM)
The character blink RAM stores character blink data. A maximum of 13 characters of blink
data can be stored.
5. Arbitrator Blink RAM (ABB RAM)
The arbitrator blink RAM stores blink data of the arbitrator. Blink data is stored in 5 dot units,
and a maximum of 65 dots of blink data can be stored.
6. Character Generator ROM (CG ROM)
The character generator ROM generates character patterns with 5 7 dots. This ROM can store
a maximum of 256 types of characters, numerics, and symbols.
When an 8-bit character code of CG ROM is written to CGA RAM, character patterns with
5 7 dots corresponding to 8-bit character code are displayed at the LCD display position
corresponding to the CGA RAM address.
