Pin Functions
SCL (serial clock input) pin
SDA (serial data input/output) pin
The SCL pin is a serial clock input pin that processes signals at the rising and falling edges of SCL clock signals.
This pin must be pulled up by a resistor to the V DD level and wired-ORed with an open drain (or open collector)
output device for use.
The SDA pin is used to transfer serial data to the input/output, and it consists of a signal input pin and n-channel
transistor open drain output pin.
Like the SCL pin, the SDA pin must be pulled up by a resistor to the V DD level and wired-ORed with an open drain
(or open collector) output device for use.
