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”.
In the S-24C16C, successive 3 bits (P2, P1, 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, and
700h to 7FFh).
