In I2C bus, the front part of each frame of data contains the address information

and blue patches are used to represent the address ID. In the ID, "Write" is used

to represent writing address and "Read" is used to represent reading address.

Press ADDR to select "Normal" or "R/W". When "R/W" is selected, "AddrBits"

will include the "R/W" bit as a part of the address value.
