4.3 UART0 (JP: 2, 3, 4)
One RS232-transceiver (U2, X5) can be connected to the microcontrollers UART interface 0.
JP2, JP3 connect UART 0 to the RS232 transceiver (U2, X5)
JP4
Some programs (e.g. Terminals) need a connection between CTS and RTS
Jumper
JP2 (SIN0)
JP3 (SOT0)
JP4 (RTS-CTS)
By default, UART0 (SIN0/SOT0) is connected to X5.
UART0 is also used for asynchronous in-circuit Flash programming.
4.4 UART1 (JP: 12, 14, 15)
One RS232-transceiver (U3, X6) can be connected to the microcontrollers UART interface 1.
JP12, JP14
connect UART 1 to the RS232 transceiver (U3, X6)
JP15
Some programs (e.g. Terminals) need a connection between CTS and RTS
Jumper
JP12 (SIN1)
JP14 (SOT1)
JP15 (RTS-CTS)
By default, UART1 (SIN1/SOT1) is connected to X6.
