SBOS891B October 2018 – April 2021 TMP144
The host can initiate a global software reset command (C[7:0] = 10110100) to all TMP144 devices in the daisy-chain as shown in Figure 7-6. Upon receiving this command, the TMP144 resets all of its internal registers except for the device ID and reconnects the bus. If the bus is broken before the initiation of this command, all TMP144 devices before the broken bus point receive the command. If the host intends to initiate a global software reset across all TMP144 devices in the chain, this command must be transmitted multiple times until it echoes back to the host.
