Block Functions
AC (Address counter)
AC is a counter that provides the DCRAM address.
The address is automatically modified internally, and the LCD display state is retained.
DCRAM (Data control RAM)
DCRAM is the RAM that is used to store display data expressed as 8-bit character codes. (These character codes are
converted to 5
DCRAM has a capacity of 64 8 bits, and can hold 64 characters. The table below lists the correspondence between the
6-bit DCRAM address loaded into AC and the display position on the LCD panel.
For a 64 digits
When the DCRAM address loaded into AC is 00H
However, when the display smooth scrolling is performed, the DCRAM address shifts as follows.
Note that the display area on the LCD is display digits 1 to 16 on the first line when a display technique is 5 7, 5 8,
or 5
For a 32 digits
When the DCRAM address loaded into AC is 00H
However, when the display smooth scrolling is performed, the DCRAM address shifts as follows.
Note that the display area on the LCD is display digits 1 to 16 on the first line when a display technique is 5 7, 5 8,
or 5
