This is implemented using the J8 & J9 jumpers. For example, to use the USB interface, the J8 and J9 jumpers must first select the USB mode and J4~7 & J24 must also be connected. Additionally, the USART to SPI mode must be configured by software to control the USB bridge (HT45B0K) to implement a USB function.
