Have you set the CAN module to disable/sleep mode first?

I have tried

CAN_OP_LISTEN
CAN_OP_DISABLE
CAN_OP_CONFIG

like this:

can_set_mode(CAN_OP_DISABLE);
sleep();

...

-Tried with real CAN device which is trying to send data.
-Measured if the receive pin of the microcontroller changes when making the canbus dominant. This is okay.
-Did read back if the:

C1INTE. ...

I thought the CANbus would wake-up when there is a puls on the RXD pin. So that assumption is not correct?

I also did read this:

CiINTE: ECAN Interrupt Enable Register
This register selectively ...

OK. Yes if the delta V between the lines is <0.6v this is the recessive state.

You don't show what is in front of this code?. You do realise you have to switch to config mode _before_ you can sw ...

Is the bus idle?.

It'll only go into disable mode after 11 recessive bits on the bus.

If the REQOP<2:0> bits (CiCTRL1<10:8>) = 001, the
module enters the Module Disable mode. If ...

On CAN, you have to put the module into 'disable' mode, and then when you go to sleep the module automatically goes into recessive mode on the bus. When there is bus activity, this triggers the CAN wa ...

You should be able to use the same trick to monitor the CAN data line and wake up on message. You need to configure the CAN RX data pin to be an external interrupt during sleep and reconfigure it to b ...

The example for this is ex_cni.c

This is the input change peripheral. Nothing to do with INT_EXT.

They show how to map the peripheral to up to three pins at the same time (so it'd trigger on any ...

Thank you all for the help so far,

It is allowed for the CAN-bus to take some time.

I started with the push button. I have got a test board with a 24HJ128GP502.

I get the idea the code needs ...

Hello,
I want to make use of the sleep mode.
When a Pin is made high (RC5 pin38) the uC must wake up .
When there is can-bus traffic the uc must also wake up.
Can some one please tell me what to ...
