I have a S32K144 EVB board.These days I want to use CAN bus and I have read the " S32K14x Series Reference Manual". It seems that I can use CAN by configuring the register in S32K144 according to the " Reference Manual". But,the example for S32K144 in S32DS have something about "MC333903", but I can not find anything about "MC333903" in the " Reference Manual". I want to know whether I need to read other Manuals in order to use CAN bus.
Hi,
There are currently two boards FRDMPK144-Q100 and S32K144EVB-Q100.
The MC33903 is a system basis chip (SBC) with CAN transceiver on FRDMPK144-Q100.
Whereas S32K144EVB-Q100 has UJA1169. Both chips are configurable via SPI.
You can configure only FlexCAN (output/input on CAN_RX, CAN_TX) using S32K144 registers. But if you need CAN interface (CAN_HI, CAN_LO) you need the SBC or other CAN transceiver.
Regards,
Daniel
