C Bus
2.2.1
The
I
2
C-Bus interface implemented on the VPS decoder is a slave transmitter/receiver,
i.e., both reading from and writing to the VPS decoder is possible. The clock line SCL is
controlled only by the bus master usually being a micro controller, whereas the SDA line
is controlled either by the master or by the slave. A data transfer can only be initiated by
the bus master when the bus is free, i.e., both SDA and SCL lines are in a high state. As
a general rule for the
I
2
C Bus, the SDA line changes state only when the SCL line is low.
The only exception to that rule are the Start Condition and the Stop Condition. Further
Details are given below. The following abbreviations are used:
START:
Start Condition generated by master
AS:
Acknowledge by slave
AM:
Acknowledge by master
NAM:
No Acknowledge by master
STOP:
Stop condition generated by master
