Emergency Message Monitoring
Emergency messages are collected by the CAN master (when enabled) and placed into an indexed buer.
Messages can be retrieved by the NODE ID or the depth of the buer can be retrieved and messages
pulled out one-by-one.
e buer is 16 emergency messages deep.
When a “code” is retrieved from the buer, its data is placed into pre-dened global VCL variables
and the message is pulled from the stack. e user can then check for the next message until the index
returned is null (valueless).
