The function of each significant bit in a display ROM word is shown in the following table.
The line addresses in display ROM are shown in the following table.
Display ROM Configuration
The display ROM is configured as 1,536 words from
address 000H to 5FFH as shown in the following table.
Each 16-bit word contains a 7-bit character code and a
single control bit. When the control bit is 0, the 7-bit
character code is significant and is used to address the
character generator ROM, and when 1, the 7-bit character
code in ROM is ignored and the character code is read
from display RAM. The display RAM address automati-
cally increments by one each time a character code is read
from RAM. Note that your local SANYO representative
can offer advice on how to specify the generator character
ROM.
