Does the chip MCZ33903CD5EK has enable bit when use CAN function

[Fan_xy]

Hello,

FRDM-KEA64 board,

CAN function

I use the CAN send function, i check there is signal on can_tx pin of KEA64, while there

is no signal  on CANH and CANL on MCZ33903CD5EK chip.

So i doubt whether there is a bit that need enable by manual ?

Or there is a CAN demo used on FRDM-KEA64 board ？

Thanks!

Hello Fan,

It is necessary to turn-on the 5V-CAN regulator unless the device is in Debug mode (8V-10V at the DBG pin - TP26):

This is done using 5V-can[1:0] bits:

Then you have to also set both CAN mod[1:0] bits:

I guess in CW10.7 there is CAN example code for FRDM-KEA64 board.

Hope it helps.

Best regards,

Tomas
