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
Setting
Description
JP1 (UART”A”TxD)
ON (closed)
SOT1 is connected to RS232-Transceiver
OFF (open)
SOT1 is disconnected from RS232-Transceiver
JP2 (UART”A”RxD)
ON (closed)
SIN1 is connected to RS232-Transceiver
OFF (open)
SIN1 is disconnected from RS232-Transceiver
JP31 (RTS-CTS)
ON (closed)
RTS and CTS is shortcut on X3
OFF (open)
RTS and CTS is not shortcut on X3
Default: JP1=ON, JP2=ON, JP31 = ON
By default, UART1 of MB90F387 is use
d 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
Setting
Description
JP6 (UART”B”RxD)
ON (closed)
SIN0 is connected to RS232-Transceiver
OFF (open)
SIN0 is disconnected from RS232-Transceiver
JP8 (UART”B”TxD)
ON (closed)
SOT0 is connected to RS232-Transceiver
OFF (open)
SOT0 is disconnected from RS232-Transceiver
JP32 (RTS-CTS)
ON (closed)
RTS and CTS is shortcut on X5
OFF (open)
RTS and CTS is not shortcut on X5
Default: JP6=OFF, JP8=OFF, JP32 = OFF
By default, UART0 is not connected. (UART0 would only be available for MB90360,
MB90895, and MB90960 Series)
