Section 19 Pin Function Controller (PFC)
19.4 Usage Notes
The multiplexed pins listed in tables 19.1 to 19.6 except pins PB2, PB3, PE7, and PF0 to PF7
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.
