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)

Note: All write-capable registers are retained registers, see POWER - Power control on page 67 for more information.

The input buffer of a GPIO pin 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 on page 163. Inputs 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 on page 163.

Selected pins also support analog input signals, see ANAIN in GPIO port and the GPIO pin details on page 163. The assignment of the analog pins can be found in Pin assignments on page 518.

The following delays should be taken into considerations:

• There is a delay of 2 CPU clock cycles from the GPIO pad to the IN register.
• The GPIO pad must be low (or high depending on the SENSE polarity) for 3 CPU clock cycles after DETECT has gone high to generate a new DETECT signal.

Note: When a pin is configured as digital input, care has been taken to minimize increased current consumption when the input voltage is between VIL and VIH. However, it is a good practice to ensure that the external circuitry does not drive that pin to levels between VIL and VIH for a long period of time.

Maximum ratings are the extreme limits to which the chip can be exposed for a limited amount of time without permanently damaging it. Exposure to absolute maximum ratings for prolonged periods of time may affect the reliability of the device.
