3804 Group (Spec.L)
MULTI-MASTER I2C-BUS INTERFACE
The 3804 group (Spec. L) has the multi-master I2C-BUS
interface. The multi-master I2C-BUS interface is a serial
communications circuit, conforming to the Philips I2C-BUS data
transfer format. This interface, offering both arbitration lost
detection and a synchronous functions, is useful for the multi-
master serial communications.
functions.
This multi-master I2C-BUS interface consists of the I2C slave
address registers 0 to 2, the I2C data shift register, the I2C clock
control register, the I2C control register, the I2C status register,
the I2C START/STOP condition control register, the I2C special
mode control register, the I2C special mode status register, and
other control circuits.
When using the multi-master I2C-BUS interface, set 1 MHz or
more to the internal clock
φ.
System clock
φ = f(XIN)/2 (high-speed mode)
φ = f(XIN)/8 (middle-speed mode)
NOTE:
1. We are not responsible for any third party’s infringement of
patent rights or other rights attributable to the use of the
control function (bit 6 of the I2C control register at address
002E16) for connections between the I2C-BUS interface and
ports (SCL1, SCL2, SDA1, and SDA2).
