In the loop back mode of the CAN MCP25625, if we load and send data on the TXB0 buffer are we supposed to receive a RXB0 buffer ready and filled with data in the TXB0 buffer?

If yes, following are the steps that I am doing:

1. Send MCP25625 to LOOPBACK MODE by setting the bits 7:5 for sequence 010, given in the datasheet. I reverify by checking up the CAN Status bits and the bits 7:5 show me a 010.
2. After I successfully load and send the data onto TXB0, I don't receive a message ready signal which is why I am unable to check the RXB0 buffer. On force checking it I find that the data is junk i.e. the LoopBack functionality did not perform.

What else I should check to debug this?

The way I am checking this is with the USB MCP2210 SPI behaving as master and using that to drive the MCP 25625 slave device.

If anyone has worked with the CAN MCP25625 chip in the past I would like to know if in the loop back mode if we load and send data on the TXB0 buffer are we supposed to receive a RXB0 buffer ready and filled with data in the TXB0 buffer?

Does anyone have an insight on what else I should check to debug this? Has anyone run into trouble with this earlier.
