IIC is a two wire serial interface developed, the bus consists of a clock line(SCL) and a data line(SDA)

with pull-up structures. The LP62

99 works as a slave mode, and address can set by Addr pin. The data

transfer protocol is follow IIC-Bus Specification's standard mode(100kbps) and fast mode(400kbps).
