Pad Descriptions
1.2.1
SDA (Serial Data)
This is a bi-directional pad used to transfer addresses
and data into and data out of the device. It is an open
drain terminal, therefore the SDA bus requires a pull-up
resistor to V

(typical 10 K
400 kHz).
For normal data transfer SDA is allowed to change only
during SCL low. Changes during SCL high are reserved
for indicating the START and STOP conditions.
