gpio_cpu_configure - override defaults?

gpio_cpu_configure is called often to update the pin configurations.

One problem.

It assumes GPIO or Alternate Function 2 for most (well I care about PORT TC) functions.

How do you select a different non-GPIO function?

If the pin usage is generally GPIO or non-GPIO maybe the BSP should add a table to define the Alt function.

Or is there a clean up function that can be called after gpio_cpu_configure() to fix the 'errors' induced?

I am using DTIM0 as a clock output... searching ther code I do not see anything in MQX that uses any of the DTIM registers

Ok after digging deeper I see that the code I was looking at leaves the bits alone that are not assigned as GPIO.

I just set the PAR bits and all is well.
