Good morning
I refer to K20P100M72SF1RM.pdf.
There are two others K20 RM all of them have the same inconsistency it seems to me
The section
5.7.4 PORT digital filter clocking
is referring to the clock for the digital filter input.
The register PORTx_DFCR[CS] is referred.
The problem is no one of the K20 RM mention the DFCR register. It seems the DFCR and the DRWR are not in use in this processor.
I define in the project the macro CPU_MK20DX256VLK10.
This will include the files
MK20D10.h
and
MK20D10_features.h
This last has the macro
FSL_FEATURE_PORT_HAS_DIGITAL_FILTER
enabling the DFER, DFCR and DFWR
Something is not in order in the SDK. Please have a look.
Thank You
Pietro
