This code works if the H register has been pushed onto the stack in the break
service routine software. This code should be executed at the end of the break
service routine software.

Address:
This register contains six flags that show the source of the last reset.
Clear the SIM reset status register by reading it. A power-on reset sets
the POR bit and clears all other bits in the register.
POR — Power-On Reset Bit
PIN — External Reset Bit
Read:
Write:
POR:
1 = Last reset caused by POR circuit
0 = Read of SRSR
1 = Last reset caused by external reset pin (RST)
0 = POR or read of SRSR

;If RETURNLO is not zero,
;then just decrement low byte.
;Else deal with high byte, too.
;Point to WAIT/STOP opcode.
;Restore H register.
See if wait mode or stop mode was exited by
break.
