While this is not the first time the debugger shell has been discussed, I found this so handy while debugging Kinetis code as these processors have many registers many of which I am new to. Digging thru the register tab gets time consuming, and then the IDE will "helpfully" close the register view you had open, I find this an invaluable feature. The decode feature is great!
If you open the Debugger Shell View (Window/Show View/Debugger Shell you may have to look in "other") you can type:
display "PORTA_PCR0" -d display "GPIOB_PDDR" display "GPIOB_PDDR" -d display "Analog-to-Digital Converter (ADC0)" -d display NVIC_ISER -d display NVIC_IPR0 reg -regset (show other possible register sets, some of which may not work??)
If you use -d you will also see a complete decode of the registers contents.
I have also found if you look in the header file you can find the proper what to get the register you want.
Wow! What a time saver!
