    AM67 processor pin A24 can be either GPIO or SDWP.  The various pin modes for each pin are defined in the data manual.  If the pin is connected to PMIC, likely used as GPIO.   Each LVCMOS pin has a pad configuration register (location also provided in data manual).  From snip-it below, you can see the various pin modes supported (MUX MODE setting) and the pad config register (PADCONFIG145).
