FUNCTIONAL DESCRIPTION
4-1.
ADDRESS COUNTER (AC)
The AC stores the address of the data being written to and from DDRAM or CGRAM. The
AC increments by 1 (overflows from 27H to 40H and from 67H to 00H) or decrements by
1 (underflows from 40H to 27H and from 00H to 67H) after each DDRAM access. The
AC increments by 1 (overflows from 3FH to 00H) or decrements by 1 (underflows from
00H to 3FH) after each CGRAM access. When addressing DDRAM, the value in the AC
also represents the cursor position.
4-2.
DISPLAY DATA RAM (DDRAM)
The DDRAM stores the character code of each character being displayed on the VFD.
Valid DDRAM addresses are 00H to 27H and 40H to 67H. DDRAM not being used for
display characters can be used as general purpose RAM. The tables below show the
relationship between the DDRAM address and the character position on the VFD before
and after a display shift (with the number of display lines set to 2).
Relationship before a display shift (non-shifted):
