(PIODO). The PIO Open Drain Control Register (PIOOD) can select whether each bit is either an open
drain output or a totem pole output.
regardless of the pin direction settings.
Of the 16-bit PIO signals, signals PIO[15:8] can be used in combination with 8-bit ECC check bit
The four following registers are used to control the PIO port.
PIO signals can be selected by the PIO Direction Control Register (PIODIR) for each bit as either
Signals selected as output signals output the values written into the PIO Data Output Register
PIO signal status is indicated by the PIO Data Input Register. This register can be read out at any time
