A multidrop configuration is a configuration of multiple devices in a system communicating through UART to the host system. There is no daisy-chain communication between devices. When [MULTIDROP] = 1, the device COMH and COML ports are disabled. All the communication protocols, single device read/write, broadcast read/write, stack read/write, reverse broadcast write are still supported as in daisy-chain configuration (that is, [MULTIDROP] = 0). However, in a multidrop configuration, it is unlikely to have a use of the stack and reverse broadcast commands. If broadcast command is used, it is still required to set up the devices with sequential device address and set the [TOP_STACK] bit on the device with highest device address. The device with [TOP_STACK] = 1 will initiate the data return when a broadcast read command is received, and the device with one lower device address will respond next, as in a daisy-chain communication. Additionally, a COMM_CLR must be used before every frame to ensure consistent communication in multidrop configuration.
