10.1.5 I/O Characteristics

The device features two types of Input/Output (I/O) circuits:

  • GPIO
  • DDRIO

Unless otherwise specified:

  • The following specifications apply to the GPIO type.
  • VDD refers to the voltage of the associated power rail of the I/O line, as defined in the Pin Description table. For example, for PA2, VDD refers to the voltage applied on VDDIOP0.
  • The GPIO type drive and slewrate controls are set in the PIO_DRIVE and PIO_SLEWR registers, respectively.
