Cannot read VREF registers

I cannot access the VREF_SC register in KDS 3.20.  When I select EmbSys Register => VREF => VREF => SC, I get the message "WARNING: Failed to read memory @ address 0x40074001"


My environment:

  • Mac OS X 10.12.2
  • KDS 3.2.0
  • FRDM-KL27Z development board with KL27Z64VLH4 processor
  • Segger

In KDS, in the EmbSys Registers tile, it shows

Arch: SVD(CMSIS) Vendor: Freescale Chip: MLK27Z4 Board: --- none ---

... I believe this is correct.  When I select Register VREF => VREF=> SC, in the console it prints:

WARNING: Failed to read memory @ address 0x40074001

... and the result is blank.

Note that it IS capable of printing other registers, e.g. ADC control registers, etc.


Any idea why this is failing, or how I can read the state of VREF_SC[VREFEN]?
