Bits [15–0]—PDIR [15–0] PIO Direction 0 Bits → For each bit, if the value is 1, the pin
is configured as an input. If 0, as an output. The values of these bits correspond to those
in the PIO data registers and PIO mode registers.
Bits [15–0]—PDIR [31–16] PIO Direction 1 Bits → For each bit, if the value is 1, the pin
is configured as an input. If 0, as an output. The values of these bits correspond to those
in the PIO data registers and PIO mode registers.
5.1.29 PMODE1 (076h) and PMODE0 (070h)
PIO MODE Registers. Each PIO pin is configured as an input or an output by the corresponding
bit in the PIO direction register. The bit number of PMODE corresponds to the PIO number (see
Table 46, PIO Mode and PIO Direction Settings). The value of the PMODE0 register is 0000h
at reset (see Table 49).
