MULTI-MASTER I
2
C-BUS INTERFACE
The multi-master I
2
C-BUS interface is a serial communications cir-
cuit, conforming to the Philips I
2
C-BUS data transfer format. This
interface, offering both arbitration lost detection and a synchronous
functions, is useful for the multi-master serial communications.
Figure 23 shows a block diagram of the multi-master I

C-BUS inter-
face and Table 2 shows multi-master I
2
C-BUS interface functions.
This multi-master I
