58.5 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
    • the DDRIO type when these I/Os are not driven by the MPDDRC
  • 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 DRIVE and SLEWRATE controls for the GPIO type are set in PIO_DRIVE and PIO_SLEWR registers, respectively. The DRIVE control for the DDRIO type is set in the SFR_CCFG_EBICSA register.
