Section 25 Pin Function Controller (PFC)
25.4 Usage Notes
The multiplexed pins listed in tables 25.1 to 25.6 except pins PA0 to PA7 and PB0 to PB7 include
weak keepers in their I/O buffers to prevent the pins from floating into intermediate voltage levels.
However, note that the voltage retained in the high-impedance state may fluctuate due to noise.
