I tried the peripheral register view in MCUXpress for the first time today and had difficulties due to the fact that it looks to display ADC content incorrectly.
This is a screen shot of what get
The first ones look messed up. SC1A should be at 0x40066000, SC1B at 0x40066004, SC1 doesn't exist and so should not be at 0x4006600c.
I have MCUXpresso IDE v10.0.0 [Build 344] [2017-03-21] so maybe there have been files in the meantime (?).
Also, the CPU registers default to decimal format, which means that all need to be re-formated to hex (unless one can think in decimal for registers) - if I remember correctly KDS also used to do this (the decimal view defaulting) when in its initial releases but was improved/corrected quite quickly.
