LIN configuration (P21, P25)
To provide signal translation, the EVB LIN interface (see
) has a transceiver (U9), which is:
•
Configured as Master by default (for Slave mode, remove resistor R79 as per
Table 15
),
•
Connected to a standard 4-pin Molex connector (P25) shown in
and used on most other
Freescale EVBs supporting LIN,
•
Powered either from LIN line or from local 12V via the 2-pin header (P21 as per
Table 15
).

MAC (Ethernet) interface (J10)
The installed Vybrid device features two MAC interfaces, #0 and #1, used as follows:
•
#0 is used in the RMII (Reduced MII) mode and routed to a board-to-board connector (J10) with
type and pinout defined in the DOC-01898 document; a relevant daughtercard, e.g.
IMXAI2ETH-SMSC (see
), can be plugged into it,
•
Pins of the other one are used for other functions
