Uart"A" (Jp: 1, 2, 31); Uart"B" (Jp: 6, 8, 32) - Fujitsu F2MC-16FX Series User Manual

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
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
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.
