Note:
PIC16F648A Silicon Rev. A1.
When using the EC OSC mode at frequencies
>4 MHz and temperatures >85°C, the part may
execute incorrectly from the program memory,
causing malfunction.
This problem only affects E-temp parts. Industrial
grade parts are unaffected. HS mode should be
used for frequencies >4 MHz at extended temps.
All other clock modes work to their specified
ranges.
