AD0,
AD2
Address Inputs. Select device slave address with AD0 and AD2. Connect AD0 and
AD2 to either GND, V+, SCL, or SDA to give four logic combinations (see Table 3).
216
RST
Reset Input, Active Low. Drive RST low to clear the 2-wire interface.

O0, O1,
O6, O7
Output Ports. O0, O1, O6, and O7 are push-pull outputs.
6, 7, 9, 10
4, 5, 7, 8
P2–P5
I/O Ports. P2 to P5 are open-drain I/Os rated to +6V, 20mA.
