According to DSP56374's datasheet, EXTAL is not 5V tolerant (see page 6, table
3, note 1 and page 7, table 7), however it would be simple to adapt voltage
levels with a two resistor voltage divider.
>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?
