FTDI

The FTDI chip U12 converts signals from USB2 to a variety of standard serial and parallel interfaces. Refer to the FTDI data sheet to get information about the capacity of the FT2232H chip. FTDI FT2232H chip is used in MPPSE mode for JTAG, 2 I/O's of Channel B are routed to B2B J17 and must be used as UART.

The configuration of FTDI FT2232H chip is pre-programmed on the EEPROM U9.
