AC0 to AC7: DCRAM write data (character code)

AC0 ....................LSB

AC7 ....................MSB

This instruction writes the 8 bits of data AC0 to AC7 to DCRAM. This data is a character code (see Tables 3 to 5)

and is converted to 5 × 7 dot matrix display data using CGROM and CGRAM.

8. ADRAM data write..............................<Specifies the ADRAM address and stores data at that address.>

Code

AD1 to AD8: ADATA display data

There are 8 bits of additional display data, referred to as ADATA, in addition to the 5 × 7 dot matrix of display data

(MDATA). This data is used to generate arbitrary dot patterns without using CGROM or CGRAM. The figures show

the correspondence between these data types. In particular, when ADn = 1 (where n is an integer between 1 and 8),

the dot AAn will be turned on.
