Uart 4 (Flash Programming) - Fujitsu SK-91F467D-208PFV User Manual

3.4.2 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, whether SIN4 is connected to RS-232- or LIN-transceiver
JP65 Select, whether SOT4 is connected to RS-232- or LIN-transceiver
JP69 Select, whether 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, whether DTR or RTS will be used for system reset generation
JP71 Enables the LIN transceiver
JP72 Selects, whether UART4 will be LIN master or LIN
slave

Note:
UART4 has to be selected with
JP57 to generates a system reset
Note:
UART4 is used as serial interface
for Softune Workbench Monitor
Debugger. Jumper J58 must be
closed.
