Circuit suggestion
2.2.3 UART interface RX_BT, TX_BT, RTS#_BT and CTS#_BT
The interface serves for communication with the AMB2300. Hardware handshake is used
(RTS/CTS). If this should not be supported by the host system, RTS#_BT and CTS#_BT must
be short circuit or CTS#_BT put on Low levels. This can lead however to data loss due to
overrun! We recommended therefore urgently to use handshake.
