7.5.2 PMBus Address Selection

The PMBus slave address is set by the voltage on the ADDR pin and is selected with a resistor from the ADDR pin to GND. Refer to Table 7-5.

Note that TPSM831D31 uses 7 bit addressing, per the SMBus specification. Users communicating to the device using generic I²C drivers should be aware that these 7 bits occupy the most significant bits of the first byte in each transaction, with the least significant bit being the data direction bit (0 for write operations, 1 for read operations). That is, for read transactions, the address byte is A₆A₅A₄A₃A₂A₁A₀1 and for write operations the address byte is A₆A₅A₄A₃A₂A₁A₀0. Refer to the SMBus specification for more information.
