MK60 Processor Expert Generation v.s Specification for NFC

I am observing differences between what being configured in PE v.s. what is on the spec.

I select NFC clock to be 15 MHz.  From PE, it showed that the clock is derived from PLL and divided down.  The generated codes seems to match with the specification, but not matching with what displayed on PE.


attachments 1 showed the clock selection (derived from PLL => bus clock) and the generated codes.  Attachment 2 + 3 showed that the generated codes configured NFC SRC to be 3 which is OSC clock and NFC_CLKSEL to be 1 which is external clock.  However, this is not true.  Is there a problem with the specification?  The NFC clock measured on scope seems to be matching with what was configured by PE.


can you please clarify?  This is KDS 3.0 and KSDK 1.3.
