Fujitsu MB88121 SERIES, MB91460 SERIES manual Uart 4 Flash programming, UART4 Settings

Note:

UART4 has to be selected with JP57, to generates a system reset

3.8.2 UART 4 (Flash programming)

UART4 (connector X4) is selected as RS-232 at default setting. UART4 is also used to write user software into the Flash of the MCU.

JP60 Select, if SIN4 is connected to RS-232- or LIN-transceiver JP65 Select, if SOT4 is connected to RS-232- or LIN-transceiver

JP69 Select, if RS-232- or LIN-transceiver is connected to X4 pin2 (shared pin) JP58 Some terminal programs needs a connection between CTS and RTS JP64 Selects, if DTR or RTS will be used for system reset generation

JP71 Enables the LIN transceiver

JP72 Selects, if UART4 will be LIN master or LIN slave

Jumper			Setting	Description
JP60			1-2	MCU SIN4 connected to RS-232 transceiver
		2-3		MCU SIN4 connected to LIN transceiver
JP65			1-2	MCU SOT4 connected to RS-232 transceiver
		2-3		MCU SOT4 connected to LIN transceiver
JP69			1-2	X4 pin2 is connected to RS-232 transceiver
		2-3		X4 pin2 is connected to LIN transceiver
JP58			ON (closed)	RTS and CTS is connected at connector X4
			OFF (open)	RTS and CTS is not connected at connector X4
JP64		1-2		DTR can be used for system reset
		2-3		RTS can be used for system reset
JP71			ON (closed)	LIN transceiver is enabled
			OFF (open)	LIN transceiver is not enabled
JP72			ON (closed)	LIN master mode
			OFF (open)	LIN slave mode
Default:
