3.6 UART"A" (JP: 1, 2, 31)
One RS232-transceiver can be connected to UART1.
JP1, JP2 connects UART1 to the RS232-transceiver (U1, X3)
JP31
Some Flash-programming-Tools needs a connection between CTS and RTS
Jumper
JP1 (UART"A"TxD)
JP2 (UART"A"RxD)
JP31 (RTS-CTS)
Default: JP1=ON, JP2=ON, JP31 = ON
By default, UART1 of MB90F387 is used as UART"A".
Note: RS232- and LIN-transceiver can not be used at the same time. Take care that the
jumpers JP21 and JP22 are open if JP1 and JP2 are closed.
3.7 UART"B" (JP: 6, 8, 32)
One RS232-transceiver can be connected to UART0 (only MB90360, MB90895, and
MB90960 Series).
JP6, JP8 connects UART0 to the RS232-transceiver (U3, X5)
JP32
Some tools need a connection between CTS and RTS
Jumper
JP6 (UART"B"RxD)
JP8 (UART"B"TxD)
JP32 (RTS-CTS)
Default: JP6=OFF, JP8=OFF, JP32 = OFF
By default, UART0 is not connected. (UART0 would only be available for MB90360,
MB90895, and MB90960 Series)
