6.6. Controller Area Network (CAN) Interface (J25)
A DB-9 (J25) connector is provided to facilitate serial connections to the CAN interface on the C8051040. In addi-
tion, when a shorting block is installed on header J7, writing a logic 'high' to port pin P4.2 will place the CAN trans-
ceiver in low-current standby mode. Also, resistor R12 may be replaced with a higher value to control the slew rate
of the CAN_H and CAN_L signals. See the TI SN65HVD230 data sheet for further information. Table 5 listes the pin
descriptions for J25.

6.7. PORT I/O Connectors (J12 - J19)
In addition to all port I/O signals being routed to the 96-pin expansion connector, each of the eight parallel ports of
the C8051F040 has its own 10-pin header connector. Each connector provides a pin for the corresponding port
pins 0-7, +3.3VDC and digital ground. Table 6 defines the pins for the port connectors. The same pin-out order is
used for all of the port connectors.
