IICXn - IICn function expansion registers
The IICXn registers provide additional transfer data rate configuration in fast-
speed mode. Setting of the IICXn.CLXn is performed in combination with the
IICCLn.SMCn, IICCLn.CLn[1:0], OCKSn.OCKSTHn and OCKSn.OCKSn[1:0]
(refer to “Transfer rate setting“ on page 590)
This register can be read/written in 8-bit or 1-bit units.
