Data Sheet
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
1x00
Output signal OH is controlled by hardware.
Type: Indicates the pad type and its power supply domain (A, B, M, 1).
– St: Standard pad
– Sp: Special pad e.g. XTALx
– DP: Double pad - can be used as standard or high speed pad
– In: Input only pad
– PS: Power supply pad

Testmode Enable
Enables factory test modes, must be held HIGH for
normal operation (connect to
An internal pull-up device will hold this pin high
when nothing is driving it.
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 XC223xN’s debug
system. In this case, pin TRST must be driven low
once to reset the debug system.
An internal pull-down device will hold this pin low
when nothing is driving it.

JTAG Test Data Output / DAP1 Input/Output
If DAP pos. 0 or 2 is selected during start-up, an
internal pull-down device will hold this pin low
when nothing is driving it.
