Restore Defaults
Syntax:
<SOH> RD <CR>
Description:
Returns to the factory default operating parameters. The Restore Defaults
command copies the MicroTouch factory default parameters from ROM to
the non-volatile memory (NovRAM) and then executes a Reset command.
Table 8 lists the factory defaults for the MT3000 controller. The Restore
Defaults command is useful in situations where inadvertent commands to
the controller have rendered the touchscreen inoperative.

The Restore Defaults command requires approximately 75 to 100
milliseconds, plus the execution time of the Reset command (225 to 800
milliseconds). Therefore, the application program should wait and be sure it
receives the command response before issuing another command to the
controller.
After you issue a Restore Defaults command, calibrate your touchscreen
using the Calibrate Extended command.
Response:
<SOH> 0 <CR> Positive response.
