MSP432E401Y: Is it possible to use USB and both CAN interfaces simultaneously?

Josef Alt

Part Number: MSP432E401Y

My customer needs to use USB and two CAN interfaces. Pin 96 (PB1) shares USB0VBUS and CAN1Tx.

Is it possible to configure pin 96 (PB1) for CAN1Tx and at the same time use USB. If yes, are the any limitations in USB usage?

Thanks

Yes it's possible if USB is used as a dedicated host or device (that is no OTG). See the following screenshot from TRM.

Thanks,
