input or output with or without a weak pull-up or pull-down. A PIO pin can be also programmed
as an open-drain output. Each PIO pin regains default status after a POR.

If bhe_n/aden_n (IA186ES) or rfsh_n/aden_n (IA188ES) is held low during POR, these pins will revert to normal
Input with pullup when used as PIO.
Emulators use these pins and also s2_n–s0_n, res_n, nmi, clkouta, bhe_n, ale, ad15–ad0, and a16–a0.
Input with pulldown option available when used as PIO.
