Device power is supplied through the VDD line. Power supply decoupling<br />

capacitors should be placed as near as possible to the pins 1 and 8 of the<br />
device.<br />

2 C device address is 0x1D.<br />
The control signals SCL and SDA are not tolerant of voltages more than VDDIO<br />
+ 0.3V. If VDDIO is removed, then the control signals SCL and SDA will clamp<br />
any logic signals with their internal ESD protection diodes. The SDA and SCL<br />
I2C connections are open drain, and therefore usually require a pullup resistor.<br />

The interrupt source and pin settings are user-programmable through the I 2 C<br />
interface.<br />
