HARDWARE INTERFACE FOR THE COMMUNICATION LINES
The TXD and RTS lines are CMOS logic-level signals, suitable for direct connection to the pins of an UART.
Interfacing via the RS-232 port requires an addition of an inverting driver and receiver. Simple one-transistor
inverting driver and receiver can also be utilized. Contact Semtech for more details.
