2.0
The descriptions of the pins are listed in Table 2-1.
TABLE 2-1:
2.1
SDA is a bidirectional pin used to transfer addresses
and data into and out of the device. Since it is an open-
drain terminal, the SDA bus requires a pull-up resistor
to V
For normal data transfer, SDA is allowed to change
only during SCL low. Changes during SCL high are
reserved for indicating Start and Stop conditions.
2.2
The SCL input is used to synchronize the data transfer
to and from the device.
