RE: RXMODE/TXMODE

Please read the general CAN spec before trying to use Toucan.

CAN doesn't refer to bits as 0 and 1, it uses recessive and dominant.
If several nodes transmit different logic states at the same time, the
recessive bit will be blocked by the dominant bit.  This is used for
arbitration.  Usually dominant is 0.

The control bits allow you to specify whether the pin states are high or
low for dominant bits i.e.  They can invert the signal.

Hi all,
Can anyone tell me what is the significance of the TxMode/Rxmode bits in
CANCTRL0 of MPC565? what behaviour of the processor does it actually
control? what are recessive and dominant bits?

Thanks in advance.
Joydeep
