Functional Description
2.7.2
Protocol Operations (auto-mode)
In addition to address recognition all S and I frames are processed in hardware in the auto-
mode. The following functions are performed:
– update of transmit and receive counter
– evaluation of transmit and receive counter
– processing of S commands
– flow control with RR/RNR
– response generation
– recognition of protocol errors
– transmission of S commands, if an acknowledgement is not received
– continuous status query of remote station after RNR has been received
– programmable timer/repeater functions.
The processing of frames in auto-mode is described in detail in chapter 2.7.5:
Documentation of the Auto-Mode.
