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.

•

When the DCRAM address loaded into AC is 00H.

However, when the display shift is performed by specifying MDATA, the DCRAM address shifts as shown below.

Note: *3. The DCRAM addresses are expressed in hexadecimal.

Example: When the DCRAM address is 2EH.
