* This directive will invoke the fatal error handler supplied by the user
* followed by the the default one provided by the executive. The default
* error handler assumes no hardware is present to help inform the user
* of the problem. Halt stores the error code in a known register,
* disables interrupts, and halts the CPU. If the CPU does not have a
* halt instruction, it will loop to itself.
*
* Input parameters:
* the_error - fatal error status code
*
* Output parameters:
* the_error - on stack
* status register - on stack
*
* NOTE: The the_error is not necessarily a directive status code.
