Hello All, I'm trying to find out if the DSP56374 is "5 Volt" tolerant on the input EXtal pin. The DSP56371 is according to the UG - but I'm not sure if the DSP56374 is as I'd like to use an external XO. All other inputs are 5V tolerant - but I can't find anything on the clock. Does anybody know? brgrds, Paul

After RESET, I load the program memory by using the bootloader as usual. After that, my program sets the MS bit (bit 7) in the OMR in order to change the memory configuration to 2K of program memory (0x0...
