LC75811W Sanyo Semicon Device, LC75811W Datasheet - Page 13

• Manufacturer Part Number: LC75811W
• Description: 1/8 to 1/10 Duty Dot Matrix LCD Display Controller/Driver
• Manufacturer: Sanyo Semicon Device

• DCRAM data write ... <Specifies the DCRAM address and stores data at that address>
DA0 to DA5: DCRAM address
AC0 to AC7: DCRAM data (character code)
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: Setting the method of writing data to DCRAM
Notes: *13.
