Description

P407 Pin Function Control Register

Fields

PODR

Port Output Data

0 (0): Low output

1 (1): High output

PIDR

Port Input Data

0 (0): Low input

1 (1): High input

PDR

Port Direction

0 (0): Input (Functions as an input pin.)

1 (1): Output (Functions as an output pin.)

Reserved

This bit is read as 0. The write value should be 0.

PCR

Pull-up Control

0 (0): Disables an input pull-up.

1 (1): Enables an input pull-up.

Reserved

This bit is read as 0. The write value should be 0.

NCODR

N-Channel Open Drain Control

0 (0): CMOS output

1 (1): NMOS open-drain output

Reserved

These bits are read as 000. The write value should be 000.

DSCR
DSCR1

Drive Strength Control Register

0 (00): Low drive

1 (01): Middle drive

2 (10): Middle drive for IIC Fast-mode and SPI

3 (11): Setting prohibited.

Reserved

These bits are read as 00. The write value should be 00.

ISEL

IRQ input enable

0 (0): Not used as IRQn input pin

1 (1): Used as IRQn input pin

ASEL

Analog Input enable

0 (0): Used other than as analog pin

1 (1): Used as analog pin

PMR

Port Mode Control

0 (0): Uses the pin as a general I/O pin.

1 (1): Uses the pin as an I/O port for peripheral functions.

Reserved

These bits are read as 0000000. The write value should be 0000000.

PSEL

Port Function Select These bits select the peripheral function. For individual pin functions, see the MPC table

Reserved

These bits are read as 000. The write value should be 000.
