Detailed Description

Type definiton of a i2c address.

I2C Addressing Scheme

Target addresses are handled as followed:

0b111110AAAAAAAAAAus 

is treated as 10-bit addressing.

0b100001MMMAAAAAAAus 

is treated as master code with 7-bit addessing.

0b100000NNNAAAAAAAus 

is treated as 7-bit addessing.

0b0NNNNNNNNNNNNNNNus 

Indicates an invalid address. To make use of it, there is the macros

DRV_I2C_ADDRESSING_10_BIT = 0b0111100000000000us 

and

DRV_I2C_ADDRESSING_7_BIT = 0b1000000000000000us 

or one might use the structure defined. The Master Code ID has to be put into the upper three bits of the uDeviceAddress.

Symbol	Description
0b	Start of binary sequence
N	Ignore value
M	Master code id
A	Address bit
~	Bitwise NOT
us	Unsigned short (uint16_t)
