I²C timings

All timings apply to 100kbps（at Standard Mode） , 400kbps (at Fast Mode) and 3.4Mbps(at High Speed Mode).

For I²C timings, the following abbreviations are used :

*1) S&F Mode = standard and fast mode

*2) Cb = bus capacitance on SDI line

All other naming refers to I²C specification 2.1 (January 2000).

Undescribed items and symbols are compliant with the I²C specification.
