X0 to X11
and
Y0 to Y11 Phasing bit, which is always 1
Parity bit
One or two stop bits
X and Y coordinate bits.
NOTE: In Relative Mode, X11 and Y11 are the sign bits. The bit is 0 for a positive coordinate
and 1 for a negative coordinate. Furthermore, the remaining bits for a negative coordinate
are in the two’s complement form.
Bit Pad Two ASCII BCD Format
When the data tablet is in Absolute Mode, the ASCII BCD report format is:
XXXX,YYYY, F<CR>
or XXXX,YYYY,F<CR><LF>
When the data tablet is in Relative Mode, the ASCII BCD report format is:
SXXX,SYYY,F<CR>
or SXXX,SYYYY,F<CR><LF>
As shown in the above formats, the terminator can be a carriage return (<CR>) or a carriage
return and a line feed (<LF>). This is switch-selective.
NOTE: The character 9 is in the cursor/stylus flag position when a report is issued from out-
of-prox.

Coordinate sign, in Relative Mode only. For a positive coordinate, the character can be
0 through 9. For a negative coordinate, the character is a minus sign (-).
A digit of the X coordinate; each digit is an ASCII character, 0 through 9.
The delineator character, an ASCII comma.
A digit of the Y coordinate; each digit is an ASCII character, 0 through 9.
