Subject: Built-In MOS Pull-Ups in Reset
Question
Can built-in MOS pull-ups be turned on in the reset state?
Answer
In a manual reset, I/O port states are held, and therefore built-in MOS pull-ups can be turned on.
In a power-on reset, I/O ports are initialized, and therefore built-in MOS pull-up settings are
cleared.
