If both RX0 and RX1 are set, or both are clear, then neither of the RX pins will be
disconnected.
If SLEEP is set during the reception or transmission of a message, the MCAN will
generate an immediate wake-up interrupt. (This allows for a more orthogonal software
implementation on the CPU.) This will have no effect on the transfer layer, i.e. no
message will be lost or corrupted.
The CAF flag in the EEPROM control register indicates whether or not sleep mode was
entered successfully.
A node that was sleeping and has been awakened by bus activity will not be able to
receive any messages until its oscillator has started and it has found a valid end of
