+/* How to connect JLink and GR-CITRUS
+ *
+ * GR-CITRUS needs to solder some pads to enable JTAG interface.
+ * - Short the following pads individually with solder.
+ *   - J4
+ *   - J5
+ * - Short EMLE pad and 3.3V(GR-CITRUS pin name) with a wire.
+ *
+ * The pads are [the back side of GR-CITRUS](https://www.slideshare.net/MinaoYamamoto/grcitrusrx631/2).
+ * 
+ * Connect the pins between GR-CITRUS and JLink as follows.
+ * 
+ * | Function  | GR-CITRUS pin | JLink pin No.| note     |
+ * |:---------:|:-------------:|:------------:|:--------:|
+ * | VTref     |   3.3V        |   1          |          |
+ * | TRST      |   5           |   3          |          |
+ * | GND       |   GND         |   4          |          |
+ * | TDI       |   3           |   5          |          |

+/* How to connect JLink and RX65n Target and option board
+ * (For original comment https://github.com/hathach/tinyusb/pull/922#issuecomment-869786131)
+ *
+ * To enable JTAG, RX65N requires following connections on main board.
+ * - short EJ2 jumper header, to disable onboard E2L.
+ * - short EMLE(J1-2) and 3V3(J1-14 or J2-10), to enable In-Circuit Emulator.
+ *
+ * Note: For RX65N-Cloud-Kit, the option board's JTAG pins to some switches or floating.
+ * To use JLink with the option board, I think some further modifications will be necessary.
+ *
+ * | Function  | RX65N pin  | main board | option board | JLink connector |
+ * |:---------:|:----------:|:----------:|:------------:|:---------------:|
+ * | 3V3       | VCC        |   J1-14    | CN5-6        |    1            |
+ * | TRST      | P34        |   J1-16    | CN5-7        |    3            |

+ * | TMS       | P31        |   J1-19    | USER_SW      |    7            |
+ * | TCK/FINEC | P27        |   J1-21    | N/A          |    9            |

+ * | nRES      | RES#       |   J1-10    | RESET_SW     |   15            |
+ *
+ * JLink firmware needs to update to V6.96 or newer version to avoid
+ * [a bug](https://forum.segger.com/index.php/Thread/7758-SOLVED-Bug-in-JLink-from-V6-88b-regarding-RX65N)

+/* ** BOARD SETUP **
+ * 
+ * NOTE: This board has bad signal integrity so you may experience some problems.
+ * This setup assumes you have an openh743i-c Core and breakout board. For the HS
+ * examples it also assumes you have a waveshare USB3300 breakout board plugged
+ * into the ULPI PMOD header on the openh743i-c.
+ * 
+ * UART Debugging:
+ * Due to pin conflicts in the HS configuration, this BSP uses USART3 (PD8, PD9).
+ * As such, you won't be able to use the UART to USB converter on board and will
+ * require an external UART to USB converter. You could use the waveshare FT232
+ * USB UART Board (micro) but any 3.3V UART to USB converter will be fine.
+ * 
+ * Fullspeed:
+ * If VBUS sense is enabled, ensure the PA9-VBUS jumper is connected on the core
+ * board. Connect the PB6 jumper for the LED and the Wakeup - PA0 jumper for the
+ * button. Connect the USB cable to the USB connector on the core board.
+ * 
+ * High Speed:
+ * Remove all jumpers from the openh743i-c (especially the USART1 jumpers as the
+ * pins conflict). Connect the PB6 jumper for the LED and the Wakeup - PA0
+ * jumper for the button.
+ * 
+ * The reset pin on the ULPI PMOD port is not connected to the MCU. You'll need
+ * to solder a wire from the RST pin on the USB3300 to a pin of your choosing on
+ * the openh743i-c board (this example assumes you've used PD14 as specified with
+ * the ULPI_RST_PORT and ULPI_RST_PIN defines below).
+ * 
+ * Preferably power the board using the external 5VDC jack. Connect the USB cable
+ * to the USB connector on the ULPI board. Adjust delays in this file as required.
+ * 
+ * If you're having trouble, ask a question on the tinyUSB Github Discussion boards.
+ * 
+ * Have fun!
