RS232 & USB Mode
As the RS232 and USB ports share the same USART interface on the HT32F125x development
board, only one of them can be chosen. 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.
