2.1.2 I2C interface timings
(1)
All timings specifications are referred to VILmin and VIHmax voltage levels defined for the SCL and SDA pins.
(2)
The digital interface is reset if the SCL is low more than tSCLTO duration. This is the default mode at startup. The timeout can be disabled by
register setting.
(3)
A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system.
(4)
The device internally provides a hold time of at least 300 ns for the SDA signal (referred to the VIHmin of the SCL signal) to bridge the
undefined region of the falling edge of SCL.
(5)
Cb = total capacitance of one bus line in pF. If mixed with Hs-mode devices, faster fall-times according to Table 6 are allowed.
