Note: We are not responsible for any third party’s infringement of
patent rights or other rights attributable to the use of the con-
trol function (bits 6 and 7 of the I2C control register at address
00F916) for connections between the I2C-BUS interface and
ports (SCL1, SCL2, SDA1, SDA2).
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 36 shows a block diagram of the multi-master I2C-BUS inter-
face and Table 6 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.
