I'm debugging and want to inspect
CONFIG1H (CONFIGURATION REGISTER 1 HIGH)
of a PIC18F. CONFIG1H does seem to be recongized as an SFR when I enter it into the Watch window.
After stopping at a breakpoint, you can open the configuration bits window:
Window >> PIC Memory Views >> Configuration bits
but it's unclear whether those are cached in MPLABX or newly read from the MCU.
