• Bit 2—Message Transmission Status Flag (GSR2): Flag that indicates whether the module is
currently in the message transmission period. The “message transmission period” is the period
from the start of message transmission (SOF) until the end of a 3-bit intermission interval after
EOF (End of Frame). This bit cannot be modified.
