Table 7-3 : Mezzanine Card Connector P14
Please note that on the TPMC816-1x, the P14 back I/O connector is always populated and is
connected in parallel to the front I/O connectors.
Do not use these modules on carrier boards where P14/J14 is reserved for other system
signals but PMC I/O. Ask support for special board options with front I/O only in this case.
For a CAN bus channel, do either use front I/O or back I/O. Do not use both front I/O and back
I/O at the same time for a CAN bus channel.
