Addressing I
There are two address formats. The simplest is the 7-bit address format with a R/W bit
(Figure
address format, two bytes must be transmitted. The first five bits specify this to be a 10-bit
address format. The 1st transmitted byte has 5-bits which specify a 10-bit address, the two MSbs
of the address, and the R/W bit. The second byte is the remaining 8-bits of the address.
