Using the S-BUS protocol it is possible to imple-
ment mixed system including S-BUS/I

C BUS bus
peripherals. In order to have the compatibility with
the I
2
C BUS peripherals, the devices including the
S-BUS interface must have their SDA and SEN
pins connected together as shown in the following
Figure 28
(a and b). It is also possible to use mixed
S-BUS/I
2
C BUS protocols as showed in
Figure 28
(c). S-BUS peripherals will only react to S-BUS
protocol signals, while I
2
C BUS peripherals will
only react to I
2
C BUS signals. Multimaster config-
uration is not possible with the ST63xx SPI (single
master only).
