IIC trigger [optional]
IIC (Inter-Integrated Circuit BUS) integrated circuit bus. This bus is designed by NXP
(formerly PHILIPS) company. It is mostly used for master-slave communication be-
tween master controller and slave devices. It is used in small data volume occasions,
short transmission distance, any time there can only be one host, etc.
IIC address addressing mode is divided into 7-bit addressing mode and 10-bit address-
ing mode
7-bit addressing
In the 7-bit addressing process, the slave address starts to be transmitted in the first
byte after the start signal. The first 7 bits of the byte are the slave address, and the 8th
bit is the read and write bit, where 0 means write and 1 Means read.
