frame, shown in Figure A-4.
As part of the Debug C enhancement, the operation of the debug interrupt is modified as
follows:
Implementation of this revised debug interrupt handling fully supports the servicing of any
number of normal interrupt requests while in a debug interrupt service routine. The
emulator mode state bit is essentially changed to a program-visible value, stored into
memory when the exception stack frame is created, and loaded from memory by the RTE
instruction.

from the system stack. If FS1 = 1, the processor sets the emulator mode state and
resumes execution of the original debug interrupt service routine. This is signaled
externally by the generation of the PST value that originally identified the
occurrence of a debug interrupt exception, that is, PST = 0xD.
