Some DIP switches of switch S1 (S1/5 and S1/6) are used to shortcut RTS to CTS
of the corresponding serial UART interface. S1/5 is used for the UART1
interface, S1/6 is used for UART0 interface. Especially for the serial download it
is necessary to shortcut RST with CTS of UART1, otherwise a communication
error will occur.

1.4.5 Reset Generation
It is possible to use the DTR line of the UART interfaces to generate a reset for
the evaluation board. Therfore the jumpers J9 and J10 are used. Jumper J9 is used
to select whether the DTR line from UART1 or UART0 is used to generate a
reset. Jumper J10 is used to invert the polarity of the DTR line. So just change the
polarity for DTR if the reset is not generated correctly by DTR. To disconnect the
reset logic, just remove the jumper J10.
Note: If a Reset is active, the red Reset LED is lit. During normal operation
this LED should be off! If the reset LED is steadily on, change the DTR
polarity and check the power supply input voltage.
