Address Byte
4234G–SCR–01/07
The first byte to send to the device is the address byte. The device controls if the hardware
address (A2/CK, A1/RST, A0/3V pins on reset) corresponds to the address given in the
address byte (A2, A1, A0 bits).
If the level is not stable on A2/CK pin (or A1/RST pin, or A0/3V pin) at reset, the user has to send
the commands to the possible address taken by the device.
If A2/CK to A0/3V are tied to the host microcontroller and their reset values are unknown, a gen-
eral call on the TWI bus allows to reset all the AT83C24 devices and set their address after
A2/CK to A0/3V are fixed.
Up to 8 devices can be connected on the same TWI bus. Each device is configured with a differ-
ent combination on A2/CK, A1/RST, A0/3V pins. The corresponding address byte values for
read/write operations are listed below.
