NAME

DESCRIPTION
Interface Management Logic
IML
Interprets commands from the CPU, allocates the message buffers
(TBF, RBF0 and RBF1) and provides interrupts and status information to the
microcontroller.
10 bytes memory into which the CPU writes messages which are to be
transmitted over the CAN network.
RBF0 and RBF1 are each 10 bytes memories which are alternatively used to
store messages received from the CAN network.
The CPU can process one message while another is being received.
Is a sequencer, controlling the data stream between the Transmit Buffer,
Receive Buffers (parallel data) and the CAN-bus (serial data).
Synchronizes the CAN-controller to the bitstream on the CAN-bus.
Controls the output driver.
Performs the error confinement according to the CAN-protocol.
