The following bits control pins 7 through 2 of Port CAN when they are
implemented externally.
PUPCAN — Pull-Up Enable Port CAN
RDPCAN — Reduced Drive Port CAN
DDCAN7 – DDCAN2 — This bits served as memory locations since
there are no corresponding external port pins.
DDCAN6
PCAN6
Port bits 7 to 2 will read zero when configured as inputs because they
are not implemented externally.
When configured as output, port bits 7 to 2 will read the last value
written.
Reading bits 1 and 0 returns the value of the TxCan and RxCan pins,
respectively.
