I'm working from the ARM documentation on Interrupts for the FRDM KL25 and am converting to run on the FRDM KL43. The code is CMSIS-based and I'm trying to keep my code CMSIS-compatible. I ran across the setting and clearing of "Debug Port" register at the beginning and end of the example ISR. Seems to be fine for the KL25, but MCUXpresso doesn't recognize it among the header files for the KL43.
Is there an equivalent register on the KL43 for enabling/disabling debug mode on the FRDM KL43? (what I'm assuming the attached code is doing)
