13 CHARACTERISTICS FOR THE I
2
C-BUS INTERFACE
Notes
1.
2.
This parameter is determined by the user software. It must comply with the I
2
C-bus specification.
This value gives the auto-clock pulse length which meets the I
2
C-bus specification for the special crystal frequency.
Alternatively, the SCL pulse must be timed by software.
The rise time is determined by the external bus line capacitance and pull-up resistor. It must be less than 1
μ
s.
The maximum capacitance on bus lines SDA and SCL is 400 pF.
