Bit 7 = FM/SM Fast/Standard I
This bit is used to select between fast and stand-
ard mode. See the description of the following bits.
It is set and cleared by software. It is not cleared
when the peripheral is disabled (I2CCR.PE=0)
Bits 6:0 = CC[6:0] 9-bit divider programming
Implementation of a programmable clock divider.
These bits and the CC[8:7] bits of the I2CECCR
register select the speed of the bus (F

7-bit Addressing Mode
Bits 7:1 = ADD[7:1] Interface address.
These bits define the I
face.
They are not cleared when the interface is disa-
bled (I2CCR.PE=0).
Bit 0 = ADD0 Address direction bit.
This bit is don’t care; the interface acknowledges
either 0 or 1.
It is not cleared when the interface is disabled
(I2CCR.PE=0).
Note: Address 01h is always ignored.
10-bit Addressing Mode
Bits 7:0 = ADD[7:0] Interface address.
These are the least significant bits of the I
address of the interface.
They are not cleared when the interface is disa-
bled (I2CCR.PE=0).
