I'am trying to use the DAIP20 on an 21369-Ezlite-Board in an different way, therefore, i've switched OFF the PB4 (SW7, Position 4) to disconnect the PB4 from the DAIP20 Pin.
Without connected the USB and the Position 4 ON, after Power-on, the Led's 1-8 are running.
Without connected the USB and the Position 4 OFF, after Power-on, the Led's 1-8 are NOT running.
Why ist the boot-modus of the board influenced by the switch position 4 of SW7 ?
There is not so by switching off the position 1, 2 or 3 of SW7.
With the position 4 of SW7 OFF, there are also sometimes erroneous results, if you download programs from VisualDSP.
