21.5.1 UART Communication Between a Transmitter and Multiple Receiver using Address Detect Feature

A transmitter is communicating with multiple receivers as shown in Figure 21-20. When a transmitter wants to send data to any one of the receivers, it will first send the receiver's address followed by the data bytes. These data bytes will be ignored by the rest of the receivers. The mask value can also be configured so that more than one receiver can receive the same data bytes.
