16. Multi-master I2C bus Interface
The multi-master I2C bus interface is a serial communication circuit based on Philips I2C bus data transfer
format, equipped with arbitration lost detection and synchronous functions. Figure 16.1 shows a block
diagram of the multi-master I2C bus interface and Table 16.1 lists the multi-master I2C bus interface func-
tions.
The multi-master I2C bus interface consists of the S0D0 register, the S00 register, the S20 register, the
S3D0 register, the S4D0 register, the S10 register, the S2D0 register and other control circuits.
Figures 16.2
to 16.8 show the registers associated with the multi-master I2C bus.
