GPIO — General purpose input/output

The general purpose input/output pins (GPIOs) are grouped as one or more ports, with each port having up to 32 GPIOs.

The number of ports and GPIOs per port varies with product variant and package. Refer to Registers and Pin assignments for more information about the number of GPIOs that are supported.

GPIO has the following user-configurable features:

Up to 32 GPIO pins per GPIO port
Output drive strength
Internal pull-up and pull-down resistors
Wake-up from high or low level triggers on all pins
Trigger interrupt on state changes on any pin
All pins can be used by the PPI task/event system
One or more GPIO outputs can be controlled through the PPI and GPIOTE channels
Any pin can be mapped to a peripheral for layout flexibility
GPIO state changes captured on the SENSE signal can be stored by the LATCH register

The GPIO port peripheral implements up to 32 pins, PIN0 through PIN31. Each of these pins can be individually configured in the PIN_CNF[n] registers (n=0..31).

The following parameters can be configured through these registers:

Direction
Drive strength
Enabling of pull-up and pull-down resistors
Pin sensing
Input buffer disconnect
Analog input (for selected pins)

The PIN_CNF registers are retained registers. See POWER — Power supply for more information about retained registers.

Pin configuration

Pins can be individually configured through the SENSE field in the PIN_CNF[n] register to detect either a high or low level input.

When the correct level is detected on a configured pin, the sense mechanism will set the DETECT signal high. Each pin has a separate DETECT signal. Default behavior, defined by the DETECTMODE register, combines all DETECT signals from the pins in the GPIO port into one common DETECT signal and routes it through the system to be utilized by other peripherals. This mechanism is functional in both System ON and System OFF mode. See GPIO port and the GPIO pin details.

The following figure illustrates the GPIO port containing 32 individual pins, where PIN0 is shown in more detail for reference. All signals on the left side of the illustration are used by other peripherals in the system and therefore not directly available to the CPU.

Figure 1. GPIO port and the GPIO pin details

Pins should be in a level that cannot trigger the sense mechanism before being enabled. If the SENSE condition configured in the PIN_CNF registers is met when the sense mechanism is enabled, the DETECT signal will immediately go high. A PORT event is triggered if the DETECT signal was low before enabling the sense mechanism. See GPIOTE — GPIO tasks and events.

See the following peripherals for more information about how the DETECT signal is used:

POWER — Power supply - uses the DETECT signal to exit from System OFF mode.
GPIOTE — GPIO tasks and events - uses the DETECT signal to generate the PORT event.

When a pin's PINx.DETECT signal goes high, a flag is set in the LATCH register. For example, when the PIN0.DETECT signal goes high, bit 0 in the LATCH register is set to 1. If the CPU performs a clear operation on a bit in the LATCH register when the associated PINx.DETECT signal is high, the bit in the LATCH register will not be cleared. The LATCH register will only be cleared if the CPU explicitly clears it by writing a 1 to the bit that shall be cleared, i.e. the LATCH register will not be affected by a PINx.DETECT signal being set low.

The LDETECT signal will be set high when one or more bits in the LATCH register are 1. The LDETECT signal will be set low when all bits in the LATCH register are successfully cleared to 0.

If one or more bits in the LATCH register are 1 after the CPU has performed a clear operation on the LATCH register, a rising edge will be generated on the LDETECT signal. This is illustrated in DETECT signal behavior.

Note: The CPU can read the LATCH register at any time to check if a SENSE condition has been met on any of the GPIO pins. This is still valid if that condition is no longer met at the time the CPU queries the LATCH register. This mechanism will work even if the LDETECT signal is not used as the DETECT signal.

The LDETECT signal is by default not connected to the GPIO port's DETECT signal, but via the DETECTMODE register. It is possible to change from default behavior to the DETECT signal that is derived directly from the LDETECT signal. See GPIO port and the GPIO pin details. The following figure illustrates the DETECT signal behavior for these two alternatives.

A GPIO pin input buffer can be disconnected from the pin to enable power savings when the pin is not used as an input, see GPIO port and the GPIO pin details. Input buffers must be connected to get a valid input value in the IN register, and for the sense mechanism to get access to the pin.

Other peripherals in the system can connect to GPIO pins and override their output value and configuration, or read their analog or digital input value. See GPIO port and the GPIO pin details.

Selected pins also support analog input signals, see ANAIN in GPIO port and the GPIO pin details. The assignment of the analog pins can be found in Pin assignments.

Note: When a pin is configured as digital input, increased current consumption occurs when the input voltage is between V_IL and V_IH. It is good practice to ensure that the external circuitry does not drive that pin to levels between V_IL and V_IH for a long period of time.
