Block Functions
AC (address counter)
AC is a counter that provides the addresses used for DCRAM and ADRAM.
The address is automatically modified internally, and the LCD display state is retained.
DCRAM (data control RAM)
DCRAM is RAM that is used to store display data expressed as 8-bit character codes. (These character codes are
converted to 5

7, 5
×
8, or 5
×
9 dot matrix character patterns using CGROM or CGRAM.) DCRAM has a capacity of
48
×
8 bits, and can hold 48 characters. The table below lists the correspondence between the 6-bit DCRAM address
loaded into AC and the display position on the LCD panel.
