Control Response
The control response is generated automatically.
It has the following structure.
The address is defined by the value stored in XAD1 (1-byte address) or XAD1 and XAD2
(2-byte address). The control byte is fixed to 10
Transmit Direction, Response Generation
In auto-mode frames are only transmitted after the reception of a RR- or I-frame with poll
bit set.
RR-Response
The RR-response is generated automatically.
It has the following structure.
The address is defined by the value stored in XAD1 (1-byte address) or XAD1 and XAD2
(2-byte address). The control byte is fixed to 11
