AS2702 – AS-Interface Slave IC
Revision 1.3, 21-Aug-08
Page 12 of 13
AS-Interface Bus Communication
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 following 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 address 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:
I4, …, I0 (typ. data or parameters)
1 Parity Bit PB
