Screen Configuration
The character screen display is configured as 12 lines
× 24 characters, making a maximum number of 288 characters
when the smallest character size is used. The number of characters that can be displayed reduces as character size is
increased. The character screen configuration is shown in the following table.
The start address for each of the twelve display lines is specified in the display line address registers in RAM. An
example arrangement of ROM and RAM addresses is shown in the following table. Note how both the RAM and
ROM addresses increment.
