CAN1 alternate function remapping

The CAN signals can be mapped on Port A, Port B or Port D as shown in
D, remapping is not possible in devices delivered in 36-, 48- and 64-pin packages.
Alternate function
CAN1_RX or CAN_RX
CAN1_TX or CAN_RX
1. CAN1_RX and CAN1_TX in connectivity line devices; CAN_RX and CAN_TX in other devices with a single
CAN interface.
2. Remap not available on 36-pin package
3. This remapping is available only on 100-pin and 144-pin packages, when PD0 and PD1 are not remapped
on OSC-IN and OSC-OUT.

CAN2 alternate function remapping

CAN2 is available in connectivity line devices. The external signal can be remapped as
shown in
Alternate function
9.3.5

JTAG/SWD alternate function remapping

The debug interface signals are mapped on the GPIO ports as shown in
General-purpose and alternate-function I/Os (GPIOs and AFIOs)
