CAN Interface
CAN Interface
This section describes the CAN interface on the ICB-HSMC.
The board features two CAN links from the HSMC connector to two DB9 male connectors and two
10-pin headers. These two 10-pin headers share the same pins with two DB9 connectors.
Figure 3-5
shows the connections between the HSMC and the CAN interface through a CAN transceiver chip.
Figure 3-5 Wiring between HSMC and CAN interface
Table 3-3
gives the pin assignments on 10-pin headers and DB9 connectors for CAN signals.

PIO Interface
PIO Interface
This section describes the PIO interface on the ICB-HSMC.
The board has four PIO links from the HSMC connector with two 6-pin ports and one 12-pin port
(dual PIO link). The 6-pin PIO port not only provides four general-purpose I/Os but also has one
3.3V power supply and one ground pin.
Figure 3-6 gives the related schematic of the PIO
connector.
