These are special-purpose ports for key return signal inputs. Their threshold voltage is set
lower than that of other inputs. When a key matrix is formed in conjunction with ports PB
and PC, up to three simultaneous key presses can be detected.
The pull-down resistors are set up for all four pins by the IOS instruction (Pn = 2, b1). This
cannot be specified on an individual pin basis.
Input is disabled in clock stop mode.
These are special-purpose ports for key return signal outputs. No diodes for preventing
short-circuits due to multiple simultaneous key presses are required since the output
transistor circuits are unbalanced CMOS circuits.
These pins become high-impedance outputs in clock stop mode.
These pins function as high-impedance outputs after a power-on reset and retain that
state until an output instruction is executed.
