2) Threshold voltage
Description of Operation
Control Register
Programmable control can be performed for many functions of this IC.
1) Mode selection
The pin threshold voltages are set at 1/3V
In I
threshold voltages by the 3-wire/I
These threshold voltages have the following hysteresis.
SDA, SCL pin threshold voltages
In 3-wire bus mode, the threshold voltages of the logic signal input to the SDA, SCL and XSENABLE pins
have the following hysteresis.
