APPENDIX B: DEVICE I/O PINOUTS
AND FUNCTIONS
FOR MOTOR
CONTROL FAMILY
Table B-1 provides a brief description of device I/O
pinouts and the functions that may be multiplexed to a
port pin. Multiple functions may exist on one port pin.
When multiplexing occurs, the peripheral module’s
functional requirements may force an override of the
data direction of the port pin.
