/******************************************************************
*
* REASONS WHY NINDY CAN STOP EXECUTING AN APPLICATION PROGRAM
*
* When NINDY stops executing an application program that was running
* under remote host ("gdb") control, it signals the host by sending
* a single ^P. The host can then query as to the reason for the halt.
* NINDY responds with two bytes of information.
*
* The first byte is a boolean flag that indicates whether or not
* the application has exited.
*
* If the flag is true, the second byte contains the exit code.
*
* If the flag is false, the second byte contains a "reason for
* stopping" code. This file defines the possible values of that
* code.
*
* There are three categories of reasons why the halt may have occurred:
* faults, traces, and software interactions. The first two categories
* are processor-dependent; the values of these codes are tightly coupled
* to the hardware and should not be changed without first examining
* src/nindy/common/fault.c. The software interactions involve
* communication between NINDY and the host debugger; their codes are
* arbitrary.
