5. Device addressing

To start communication, the master device on the system generates a start condition to the bus line. Next, the

master device sends 7-bit device address and a 1-bit read / write instruction code on to the SDA bus.

The upper 4 bits of the device address are the "Device Code", and are fixed to "1010".

Successive 3 bits (P2, P1, and P0) are "Page Address". Choose the 8 memory blocks of 256-byte (Adress 000h to

0FFh, 100h to 1FFh, 200h to 2FFh, 300h to 3FFh, 400h to 4FFh, 500h to 5FFh, 600h to 6FFh, 700h to 7FFh).
