Note 1: To write character data into the display memory, first write into register CRA8 and then
Note 2: To read data from the display memory, first read from register CRA8, and then read from
Note 3: There should be a time interval of at least two machine cycles between a DMA set
Example: Setting a character code (020H) to the display memory (Address: 120H) and

write into registers CRA7 to CRA0. When data is written into registers CRA7 to CRA0,
DMA is incremented. It is impossible to write into the display memory for CRA7 to CRA0
alone. If no data is written into register CRA8 while data is written into registers CRA7 to
CRA0, the value previously written into register CRA8 is written into the associated
display memory.

DMA0 is incremented.

two machine cycles between a data write instruction and a data read instruction.

−: No address change at data read or write.
