This register contains the address the IIC will respond to when
addressed as a slave; note that it is not the address sent on the bus
during the address transfer

IBC5–IBC0 — IIC Bus Clock Rate 5–0
Freescale Semiconductor, Inc.
Bit 1 to bit 7 contain the specific slave address to be used by the IIC
module.
The default mode of IIC is slave mode for an address match on the
bus.
This field is used to prescale the clock for bit rate selection. The bit
clock generator is implemented as a 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
