Description

Pin Control Register n

Fields

PE

Pull Enable

0 (0): Internal pullup or pulldown resistor is not enabled on the corresponding pin.

1 (1): Internal pullup or pulldown resistor is enabled on the corresponding pin, if the pin is configured as a digital input.
PFE

Passive Filter Enable

0 (0): Passive input filter is disabled on the corresponding pin.

1 (1): Passive input filter is enabled on the corresponding pin, if the pin is configured as a digital input. Refer to the device data sheet for filter characteristics.
DSE

Drive Strength Enable

0 (0): Low drive strength is configured on the corresponding pin, if pin is configured as a digital output.

1 (1): High drive strength is configured on the corresponding pin, if pin is configured as a digital output.
MUX

Pin Mux Control

0 (000): Pin disabled (analog).

1 (001): Alternative 1 (GPIO).

2 (010): Alternative 2 (chip-specific).

3 (011): Alternative 3 (chip-specific).

4 (100): Alternative 4 (chip-specific).

5 (101): Alternative 5 (chip-specific).

6 (110): Alternative 6 (chip-specific).

7 (111): Alternative 7 (chip-specific).
IRQC

Interrupt Configuration

0 (0000): Interrupt request disabled.

8 (1000): Interrupt when logic zero.

9 (1001): Interrupt on rising edge.

10 (1010): Interrupt on falling edge.

11 (1011): Interrupt on either edge.

12 (1100): Interrupt when logic one.
ISF

Interrupt Status Flag

0 (0): Configured interrupt is not detected.

1 (1): Configured interrupt is detected. The flag remains set until a logic one is written to the flag. If the pin is configured for a level sensitive interrupt and the pin remains asserted, then the flag is set again immediately after it is cleared.
