Function
Test-System Reset Input. A high level at this pin activates
the XC164CS’s debug system. For normal system operation,
pin TRST should be held low.
Port 3 is a 14-bit bidirectional I/O port. Each pin can be
programmed for input (output driver in high-impedance
state) or output (configurable as push/pull or open drain
driver). The input threshold of Port 3 is selectable (standard
or special).
The following Port 3 pins also serve for alternate functions:
