3.5 UART"A" (JP: 1, 2, 31)

One RS232-transceiver (U1, X3) can be connected to one of the microcontroller's UART

interfaces.

JP1, JP2 connect UART 2 to the RS232-transceiver (U1, X3)

JP31

Some programs (e.g. Terminals) need a connection between CTS and RTS

Jumper

JP2 (UART"A"RxD)

JP1 (UART"A"TxD)

JP31 (RTS-CTS)

By default, UART2 is connected to UART"A".

3.6 UART"B" (JP: 6, 8, 32)

One RS232-transceiver (U3, X5) can be connected to one of the microcontroller's UART

interfaces.

JP6, JP8 connect UART 3 to the RS232-transceiver (U3, X5)

JP32

Some programs (e.g. Terminals) need a connection between CTS and RTS

Jumper

JP6 (UART"B"RxD)

JP8 (UART"B"TxD)

JP32 (RTS-CTS)

By default, UART3 is connected to UART"B".

UART "B" can be used for serial asynchronous Flash programming.
