General Device Information
Notes to Pin Definitions
1. Ctrl.: The output signal for a port pin is selected by bitfield PC in the associated
register Px_IOCRy. Output O0 is selected by setting the respective bitfield PC to
1x00_B, output O1 is selected by 1x01_B, etc.
Output signal OH is controlled by hardware.
2. Type: Indicates the pad type used (St=standard pad, Sp=special pad, DP=double
pad, In=input pad, PS=power supply) and its power supply domain (A, B, M, 1).

3 TESTM
I
In/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.

5 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 XC2766X’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.
