I just am trying to change the triggering so that my PPI triggers on the Falling edge of the clock instead of the rising edge.  While working on this I noticed that ppi.h has defines for POLC and POLFS.  While the bfin_ppi.c driver code uses POLC and POLS.

Is the "F" in POLFS actually a typo and a bug that will stop the driver from inverting POLS if that is requested?

Message: 73042    I guess it was a typo - however I think I removed this from the bfin_ppi.h header file some time ago.
