Notes to Pin Definitions
1. Ctrl.: The output signal for a port pin is selected via bitfield PC in the associated
register Px_IOCRy. Output O0 is selected by setting the respective bitfield PC to
1x00B, output O1 is selected by 1x01B, etc.
Output signal OH is controlled by hardware.
2. Type: Indicates the employed pad type (St=standard pad, Sp=special pad,
DP=double pad, In=input pad, PS=power supply) and its power supply domain (A, B,
M, 1).

In/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 XC228x’s debug system.
In this case, pin TRST must be driven low once to
reset the debug system.
