Notes: Only ch.16 and ch.17 are standard mode/high-speed mode correspondence. In ch.0, ch.1, ch.4, and ch.8 to ch.12, only a
standard mode is correspondence.
*1: R and C
L
represent the pull-up resistance and load capacitance of the SCL and SDA output lines,
respectively.
Vp shows that the power-supply voltage of the pull-up resistor and I
OL
shows the V
OL
guarantee current.
*2: The maximum t
HDDAT
only has to be met if the device does not extend the "L" width (t
LOW
) of the SCL
signal.

C bus device can be used on a standard mode I
