All slaves connected to an AS-interface bus are sequentially and cyclicly called by the master
in a string of individual transactions between the master and each slave unit.
A transaction consists of a 14 bits master request, typically containing the slave’s address as
well as data or parameter info, and an immediate acknowledging slave response of 7 bits.
The 14 bits master request - apart from Start Bit ST = 0 and End Bit EB = 1 – has the follow-
ing contents:
1 Control Bit CB: CB = 0 stands for data transfer (typ. data or parameters)
CB = 1 identifies command-type requests
5 Address Bits:
A4, …, A0
5 Information Bits:
I4, …, I0 (typ. data or parameters)
1 Parity Bit PB.
AS2702 allows for up to 62 slaves on the same AS-interface bus; this requires a slave ad-
dress extended to 6 bits, hence an extra bit beyond A4, …, A0.
Information bit I3 is used as the 6
th
address bit in this so-called extended address mode. It is
called Sel-bit, as it is perceived as to select between A-slave (Sel = 0) and B-slave (Sel = 1) at
address location A4, …, A0.
In non-extended address mode AS2702 is addressed with A4, …, A0 only - for a max. total of
31 slaves per AS-interface bus system, and is system compatible with existing slave device
AS2701A.
The 7 bits slave response – apart from Start Bit ST = 0 and End Bit EB = 1 – has the following
contents:
4 Information Bits:
1 Parity Bit PB.
I4, …, I0 (typ. data or parameters)
Detailed descriptions of all types of master requests and corresponding slave responses can
be found in AS-Interface Specification V2.11, obtainable from the AS-International Association
(D) or its local representative, see section “Application Support”.
