2.4 Virtual COM port
Serial communication is easily possible between the MK715x1 and PC. A virtual COM USB device connected
to four GPIO ports allows UART communication with or without hardware flow control. GPIO and UART line can be
completely separated by cutting the solder bridge(SB_P05, SB_P06, SB_P07, SB_P08).
