This instruction writes the 8 bits of data AC0 to AC7 to DCRAM. This data is a character code, and is converted to a
5 × 7, 5 × 8, or 5 × 9 dot matrix display data using CGROM or CGRAM.
IM: Sets the method of writing data to DCRAM
IM
DCRAM data write method
0 Normal DCRAM data write (Specifies the DCRAM address and writes the DCRAM data.)
1 Increment mode DCRAM data write (Increments the DCRAM address by +1 each time data is written to DCRAM.)
Notes: *14.
