in binary, where A2, A1, A0 are the three slave sub-address pins, and the least significant bit “RW” is the Read/Write flag.
address, allowing the device to be located anywhere within 8 slave address locations, for example from 0x30 to 0x3E.
Slave Address Decoding
The physical address for TS is different than that used by current SPD devices. The physical address for thermal sensor is “0 0 1 1 A2 A1 A0 RW”
Assuming the slave base address of the SPD+TS interface is fixed, for example at 0x30, then the pins set the sub-address bits of the slave
