An internal pullup 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 XC223[04]L’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.
