MULTI-MASTER I2C-BUS INTERFACE
The multi-master I2C-BUS interface is a circuit for serial communica-
tions conformed with the Philips I2C-BUS data transfer format. This
interface, having an arbitration lost detection function and a synchro-
nous function, is useful for serial communications of the multi-mas-
ter.
Figure 14 shows a block diagram of the multi-master I2C-BUS inter-
face and Table 2 shows multi-master I2C-BUS interface functions.
This multi-master I2C-BUS interface consists of the I2C address reg-
ister, the I2C data shift register, the I2C clock control register, the I2C
control register, the I2C status register and other control circuits.
