Initial display line register
The initial display line register assigns a DDRAM line address which corresponds to
COM0 by “Initial display line set” instruction. It is used for not only normal display but
also vertical display scrolling and page switching without changing the contents of the
DDRAM. However, the 43
th address for icon display can’t be assigned for initial display
line address.
Line counter
The line counter provides a DDRAM line address. It initializes its contents at the
switching of frame reversal signal (FR), and also counts-up in synchronization with
common timing signal.
Column address counter
The column address counter is an 8-bit preset counter which provides a DDRAM column
address, and it is independent of below-mentioned page address register.
It will increment (+1) the column address whenever “display data read” or “display data
write” instructions are issued. However, the incrementing of column address is stopped
at column address of 65H. The count-lock will be able to be released by the “column
address set” instruction again. The counter can invert the correspondence between the
column address and segment driver direction by means of “ADC select” instruction.
Page address register
The page address register provides a DDRAM page address. The page address 6 is
used for icon display, and only D0 is valid.
