Figure 32 shows an example where the FT2232D is used to interface a Philips SJA1000 CAN Bus Controller to a PC

over USB. In this example IORDY is not used and so is pulled up to Vcc. I/O1 is used to monitor the Interrupt output

(INT) of the SJA1000. The MODE pin on the SJA1000 is pulled high to select Intel mode. See the semiconductors

section of the Philips website (

www.philips.com) for more details on the SJA1000, and suitable CAN Bus transceiver

devices.
