US ( d 30h xPL xPH yPL yPH m bLen d(1)...d(bLen)
(Dot unit character display)
Code:
1Fh 28h 64h 30h xPL xPH yPL yPH m bLen d(1)...d(bLen)
xPL:
Display position x, lower byte (by 1 dot)
xPH:
Display position x, upper byte (by 1 dot)
yPL:
Display position y, lower byte (by 1 dot)
yPH:
Display position y, upper byte (by 1 dot)
m:
Response select
bLen:
Character data length
d(1)–d(bLen):
Character data / reverse select
Definable area:
0000h ≤ (xPL + xPH×100h) ≤ Max_Xdot, FFFFh
0000h ≤ (yPL + yPH×100h) ≤ Max_Ydot
00h ≤ m ≤ 01h
00h ≤ bLen ≤ FFh
00h ≤
d
≤
FFh
d=10h: Reverse OFF
d=11h: Reverse ON
Function:
Display the specified text characters at the specified (x,y) position.
Display position is specified in units of 1 dot.
For display position xP=FFFFh, write position continues from previous writes done using this
command.
The current settings for character size and table type, etc are used.
Character magnification and bold settings are not used.
If character display exceeds the bounds of the current window, only the portion within the currently-
selected window is displayed.
If Display position or Response select is outside the definable area, the command is cancelled at the
point where the error is detected, and the remaining data is treated as standard data.
Example: Display position xP=2, yP=3, 6×8 dot character “AB”

Response select m=01h: The display position of the next character is returned as response data.
If the display position would be 20 – 30 beyond the area of the currently-selected window, 0xFFFFh
is returned.
