This pin is available on dsPIC33EPXXXMC20X/50X and PIC24EPXXXMC20X devices only.

This pin is available on dsPIC33EPXXXGP/MC50X devices only.

This is the default Fault on Reset for dsPIC33EPXXXMC20X/50X and PIC24EPXXXMC20X devices. See 

 for more information.

Not all pins are available in all packages variants. See the 

 section for pin availability.

There is an internal pull-up resistor connected to the TMS pin when the JTAG interface is active. See the 
JTAGEN bit field in
