x = unknown, u = unchanged, q = value depends on condition, - = unimplemented, read as ‘0’.
Shaded cells are not used by PORTB.
This buffer is a TTL input when configured as digital I/O.
This buffer is a Schmitt Trigger input when used in Serial Programming mode.
Low-Voltage Programming must be enabled.
