3.8 Packet Traffic Arbitration (PTA) Co-existence Headers (J901 and J902)
The PIC32-BZ6 Curiosity Board provides two Packet Traffic Arbitration (PTA) headers (J901 and J902), each associated with one of the mikroBUS™ headers. Both PTA headers share the same pin assignment, as per Table 3-9, supporting software PTA for connecting the EV72E72A RNWF02 Add-on Board. For more details, refer to EV72E72A. The user can choose option 2 if option 1 is used for shared functions.
