Hardware reset
The PC Microcontroller has a button which allows you to reset the
system without turning off the power. This provides a more complete
reset than the <CTRL><ALT><DEL> method. The RESET command
also accomplishes the same thing as the reset button.
WARNING!
When using COM1 as the console, <CTRL> <ALT> <DEL>
only resets the host system. Use the RESET command to
issue a hardware reset.
≡
Reset via optically isolated input
The PC Microcontroller provides an optically isolated remote input
dedicated for generating a master reset to the system. This input is
located at the AUX I/O connector and can also be accessed on the break-
out board. See the AUX I/O chapter for more information about the
opto-isolated input on the breakout board and for an illustration of its
recommended timing usage.
