Flags to control the Unit behavior and to show the status of the Unit.
Triggers to send CAN messages on demand. Bits in the send trigger area
will send a message if the bit-value has a rising edge and the bit is asso-
ciated with an output buffer. Command messages are used to define a
send trigger area, to associate an identifier with an output buffer and a
send trigger.
Flags indicating which messages have been received. A received mes-
sage is identified by its identifier and in case a bit in the receive flags area
is associated with the received identifier, this bit is set. The message con-
tent is placed in the corresponding input buffer. Message commands are
used to define a receive flag area, to associate an identifier with an input
buffer and a receive flag.
The message content to send. Every output buffer can only have one
message.
The content of the received messages. Every input buffer can have only
one message at a time. New incoming messages will overwrite the previ-
ous content of the input buffer.
