FRDM-K64F Pinout

I would just like to inform you that I was working with the FRDM-K64F board, Rev C/Rev E to utilize a Wifi chips capabilities. After much debug it was found that the CE pin, AKA PTC12, must be routed incorrectly. A continuity check was done to find that the CE pin on the board was connected to PTB20, which is also used as a row header elsewhere. The CE pin is shown to be PTC12 in all of the documentation. This is pin 66 on the MCU. Since I was not using PTB20 I changed it in the code and it worked. It was just a pain to debug the issue with the hardware. Just something to keep in mind in the future revisions to fix. Since I found this I am wondering where the missing pin, PTC12, is routed on the board. Thank you
