14.3.1.1
IIC Address Register (IBAD)
Read and write anytime
This register contains the address the IIC bus will respond to when addressed as a slave; note that it is not
the address sent on the bus during the address transfer.

Slave Address
— Bit 1 to bit 7 contain the specific slave address to be used by the IIC bus module.The default
mode of IIC bus is slave mode for an address match on the bus.

IBC[7:0]
I Bus Clock Rate 7:0
— This field is used to prescale the clock for bit rate selection. The bit clock generator is
implemented as a prescale divider — IBC7:6, prescaled shift register — IBC5:3 select the prescaler divider and
IBC2-0 select the shift register tap point. The IBC bits are decoded to give the tap and prescale values as shown
in
