Data Sheet
As of Production Version -03
PDIR0
The value of the PDIR0 register is FC0Fh at reset.

PDIR (15 – 0)
PDIR1
The value of the PDIR1 register is FFFFh at reset.

PDIR (31 – 16)
PDIR [15:0] (bits 15-0) – PIO Direction 0 Bits. For each bit, if the value is 1, the pin is configured
as an input and as an output if the value is 0. The values of these bits correspond to those in the PIO
data registers and PIO Mode registers.
PDIR [31:16] (bits 15-0) – PIO Direction 1 Bits. For each bit, if the value is 1, the pin is configured
as an input and as an output if the value is 0. The values of these bits correspond to those in the PIO
data registers and PIO Mode registers.
PIOMODE1 (076h) - PIO MODE Registers.
PIOMODE0 (070h)
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 the table PIO Mode and PIO Direction Settings in PDIR description above.
PIOMODE0
The value of the PIOMODE0 register is 0000h at reset.

PMODE (15 – 0)
PIOMODE1
The value of the PIOMODE1 register is 0000h at reset.
