Code:
Example for 256×64 dot module:
Definable area: 00h ≤ DAD ≤ FFh
Function:
If the Write address or Write size are outside the definable area, the command (STX to sH) is
cancelled, and the display waits for the next header (STX).

02h 44h DAD 42h aL aH sXL sXH sYL sYH d(1)...d(s)
DAD: Display address
aL:
aH:
sXL: Bit image write size X, lower byte
sXH: Bit image write size X, upper byte
sYL: Bit image write size Y, lower byte
sYH: Bit image write size Y, upper byte
d(1)–d(s):
Write bit image data to the specified area.
Bit image write start address, lower byte
Bit image write start address, upper byte
0000h ≤ (aL + aH×100h) ≤ Max_DispMemAddr
0001h ≤ (sXL + sXH×100h) ≤ Xdots
0001h ≤ (sYL + sYH×100h) ≤ Ybytes
Note: X size and Y size must both be within the Display Memory area.
