Ref: http://www.nxp.com/acrobat_download/literature/9398/39340011.pdf
Page 4:
"Serial, 8-bit oriented, bi-directional data transfers can be
made at *up to* 100 kbit/s in the Standard-mode, *up to*
400 kbit/s in the Fast-mode, or *up to* 3.4 Mbit/s in the
High-speed mode"

Why do say high speed is >1000khz?
