NOTES:
1. At f
= 3.5MHz, this evaluates to 14
×
286ns = 4
μ
s, i.e., the bit-level I
2
C interface can respond to the I
2
C protocol for f
CLK
≥
3.5MHz.
2. This parameter is determined by the user software, it has to comply with the I
2
C.
3. This value gives the autoclock pulse length which meets the I
2
C specification for the specified XTAL clock frequency range. Alternatively, the
SCL pulse may be timed by software.
4. Spikes on SDA and SCL lines with a duration of less than 4
×
f
CLK
will be filtered out.
5. The rise time is determined by the external bus line capacitance and pull-up resistor, it must be
≤
1
μ
s.
6. The maximum capacitance on bus lines SDA and SCL is 400pF.
