Peripheral Simulation

For Infineon XC2264N-40F — NMI

Simulation support for this peripheral or feature is comprised of:

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

These simulation capabilities are described below.

Data 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.


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


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