Abstract

An embodiment bus device with a programmable address includes a bus communication circuit connected to a bus terminal, a first pin terminal, a memory having a first register with a first address stored therein and a second register, and a state logic circuit. The state logic circuit detects a chip select signal on the first pin terminal, receives a first message through the bus communication circuit while the chip select signal is asserted, determines that the first message indicates an address set command, and saves an address value in the first message as a second address in the second register in response to a target address in the first message matching the first address. The state logic circuit further processes a second message received through the bus communication circuit in response to a target address of the second message matching the second address.
