P-6: IIC Module
IIC is a 2-wire, bi-directional serial bus, which provides a simple, efficient
way for data exchange between devices. This two-wire bus minimizes the
interconnection between devices and eliminates the need for address
decoders.
IIC CONTROL
Every IIC device must have independent slave address. User can use
IICCON1<3:1> (ADR<2:0>) to select one independent slave address, the
map address reference follow table.
