I am currently developing a temperature control
using 56F8013, and i have a problem.
i have programed all IOs that are not being
used as input, and as soon as i start debug my program Codewarrior debug said
CCS Cable lost communication, and after that moment i have no longer acces to
DSP, i think it is because i have programed even the reset as an
input.
Does anyone knows how to erase a chip in
this state.
thanks in advance.

Steps unlock JTAG and Reset Pin
1) Device is powered OFF
2) ASSERT external RESETb
3) Device is powered ON
4) Debugger connection attempted
5) DEASSERT external RESETb
Good luck!
