Preliminary
2.13.2 FlexCAN #2 Interface
The 56F8367EVM board contains a second FlexCAN port, the CAN2_RX and CAN2_TX pins
on the 56F8367. These signals pass through an isolation jumper, JG14, before going to the CAN
physical layer interface. The EVM board uses a Phillips high-speed, 1.0Mbps, physical layer
interface chip, PCA82C250. Due to the +5.0V operating voltage of the CAN interface chip, a pull
up to +5.0V is required to level shift the transmit data output line from the 56F8367. The CAN2H
and CAN2L signals pass through inductors before attaching to the CAN bus connectors. A
primary, J22, and daisy-chain, J23, CAN connector are provided to allow easy daisy-chaining of
CAN devices. CAN bus termination of 120 ohms can be provided by adding a jumper to JG17.
Refer to
Figure 2-12 for a connection diagram and to Table 2-14 and Table 2-15 for the CAN
connector signals.
