V850ES/Fx3 – CAN it!
3.4.2 TK-V850 / FPL mode selection switch SW4/S2
SW4 switch S2 selects the TK-V850 On-Board debugging or FPL FLASH programming mode. Setting
SW4/S2 to OFF enables the TK-V850 On-Board debug function. Switching SW4/S2 to ON allows On-
Board FLASH programming by using the FPL FLASH programmer software.
For more details on how to configure V850ES/Fx3 – CAN it! in order to use On-Chip debugging please
refer to CHAPTER 5, ON-CHIP DEBUGGING.
3.4.3 UART/ LIN mode selection SW4/S3
SW4 switch S3 controls the serial communication mode of V850ES/Fx3 – CAN it! board. Setting SW4/S3
to OFF connects the UARTD0 receive and transmit signals to the FT232 interface lines and the UARTD2
receive and transmit signals to the TJA1020 LIN transceiver. Switching SW4/S3 to ON connects the
UARTD0 and UARTD2 signals vice versa.
By using the TK-V850 debugging / FPL FLASH programming mode set switch SW4/S3 to OFF. UARTD0
is reserved as communication channel for On-Board debugging or FLASH programming and can not be
used by a user program.
3.4.4 User switch SW4/S4
SW4 switch S4 is connected to port P911 of the V850ES/FG3 device. This switch can be freely used by
the user software. Switching SW4/S4 to ON applies V
