Input
In normal operation this pin must be connected directly to VDDP. If it is asserted, then the ADP goes into ICE mode.
In this mode 4 of the Decoder pins turn into ICE interface pins:
HD[7]=TMS—ICE interface mode select input
HD[6]=TDI—ICE interface data input
HD[5]=TDO—ICE interface data output
HD[4]=TCK—ICE interface clock
In this mode 4 of the Decoder pins turn into ICE interface pins:
