10. Operating Frequency and Voltage Limitation
Figure 36-3. Operating Frequnecy and Voltage Limitation
11. Inverted I/O enable does not affect Analog Comparator Output
To ensure correct operation, there is a limit on operating frequency and voltage.
on page 109
Problem fix/Workaround
None, avoid using the device outside these frequnecy and voltage limitations.
The inverted I/O pin function does not affect the Analog Comparator output function.
Problem fix/Workarund
Configure the analog comparator setup to give a inverted result (i.e. connect positive input to
the negative AC input and vice versa), or use and externel inverter to change polarity of
Analog Comparator Output.
