-   * For USB1 Device:
-   * - a 1.5Kohm pull-up resistor is needed on the USB DP data signal. There are two methods to create this.
-   * JP15 is inserted and the pull-up resistor is always enabled. Alternatively, the pull-up resistor is activated
-   * inside the USB OTG chip (U31), and this has to be done via the I2C interface of GPIO52/GPIO53. In the latter case,
-   * JP15 shall not be inserted.
-   * - J19 is the connector to use when USB Device is used. Normally it should be a USB-B connector for
-   * creating a USB Device interface, but the mini-AB connector can also be used in this case. The status
-   * of VBUS can be read via U31.
-   * - JP16 shall not be inserted.
-   *
-   * For USB1 Host:
-   * - 15Kohm pull-down resistors are needed on the USB data signals. These are activated inside the USB OTG chip (U31),
-   * and this has to be done via the I2C interface of GPIO52/GPIO53.
-   * - J20 is the connector to use when USB Host is used. In order to provide +5V to the external USB
-   * device connected to this connector (J20), channel A of U20 must be enabled. It is enabled by default
-   * since SJ5 is normally connected between pin 1-2.
-   * - LED34 lights green when +5V is available on J20.
-   * - JP15 shall not be inserted. JP16 has no effect

-/* 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          |          |
- * | TMS       |   2           |   7          |          |
- * | TCK/FINEC |   14          |   9          | short J4 |
- * | TDO       |   9           |  13          | short J5 |
- * | nRES      |   RST         |  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)
- * regarding downloading.

-/* 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            |
- * | GND       | VSS        |   J1-12    | CN5-5        |    4            |
- * | TDI       | P30        |   J1-20    | CN5-10       |    5            |
- * | TMS       | P31        |   J1-19    | USER_SW      |    7            |
- * | TCK/FINEC | P27        |   J1-21    | N/A          |    9            |
- * | TDO       | P26        |   J1-22    | CN5-9        |   13            |
- * | 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)
- * regarding downloading.

-/* ** 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!
