H
Generates an interrupt status after the receiving device has stored
the contents of the MOX register in the MOR register
Inactive interrupt status
Is generated after two consecutive inactive MX bits (end of message)
or as a result of a handshake procedure error
Indicates that the transmission is running
Results after a Monitor byte is acknowledged by the receiving device
Occurs when the receiver waits for an acknowledge of the Monitor bit
Indicates that during a transmission the receiver aborted the process
by sending an inactive ("1") MR bit value in two consecutive frames
Indicates that the transmission is running properly and that no abort
request has been activated
Indicates a transmission on the Monitor channel
Indicates that the transmitter is inactive, i.e. ready for a transmission
