    Key to Pin Definitions
    Ctrl.: The output signal for a port pin is selected by bit field PC in the associated
    register Px_IOCRy. Output O0 is selected by setting the respective bit field PC to
    1x00B, output O1 is selected by 1x01B, etc.
    Output signal OH is controlled by hardware.
    Type: Indicates the pad type and its power supply domain (B, M).
    – St: Standard pad
    – Sp: Special pad e.g. XTALx
    – DA: Digital IO and analog input
    – In: Input only pad
    – PS: Power supply pad

    TESTM
    IIn/B
    Testmode Enable
    Enables factory test modes, must be held HIGH for
    normal operation (connect to
    V
    DDPB).
    An internal pullup device will hold this pin high
    when nothing is driving it.
    3TRST
    IIn/B
    Test-System Reset Input
    For normal system operation, pin TRST should be
    held low. A high level at this pin at the rising edge
    of PORST activates the XC223[04]L’s debug
    system. In this case, pin TRST must be driven low
    once to reset the debug system.
    An internal pulldown device will hold this pin low
    when nothing is driving it.
