Example MPC5777C-SIUL_External_NMI GHS714

[#1]

********************************************************************************
* Detailed Description:
* Application performs basic initialization, initializes interrupts and NMI for
* WKPCFG pin (GPIO213).
* User needs to connect ETPUC9 pin to user switch and general purpose output
* ETPUA30 to user LED 1:
* ETPUA30 (PortP P23-15) --> USER_LED_1 (P7-1)
* WKPCFG  (PortC P10-4)  --> USER_SWITCHES (P6-4)
* Jumper J523 position 1-2 needs to be OPEN!
*
* If rising edge is detected (i.e. button is pressed), machine check exception
* is triggered and LED1 on is toggled.
*
