5 Input/output connectors and pin usage table
The table below provides details on which K65F180M pins are used to communicate with the
TWR-K65F180M sensors, LEDs, switches, and other I/O interfaces.
NOTE
Some port pins are used in multiple interfaces on-board and many are
potentially connected to off-board resources via the primary and
secondary Connectors. You must take care to avoid attempted
simultaneous usage of mutually exclusive features.
