Peripheral Simulation

VTREGs (Virtual Target Registers) which support I/O with the peripheral. 

These simulation capabilities are described below. 

NMIPIN VTREGData Type: unsigned char

THE NMIPIN VTREG contains the state of the NMI pin on the
simulated MCU.  Normally, the NMI pin is high (indicating that there
is no non-maskable interrupt condition).  NMI goes low to signal a
non-maskable interrupt.  Enter the following in the Command window to
trigger an NMI Trap using the NMIPIN VTREG. 

NMIPIN=0

Enter the following to return the NMI pin to a high level. 

NMIPIN=1

Note that on some devices the NMI pin must be low to enter Power
Down Mode.
