General Device Information

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).

6 TRST

I

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 XC238x’s debug system.

In this case, pin TRST must be driven low once to

reset the debug system.
