5V, e-stop, resume, hold, abort on version 2.11 board

Please explain the pins on the bottom of the 2.11 version board.
5V -- NC
E-STOP -- NC
RESUME -- GND
HOLD -- GND
ABORT -- GND

I am assuming that a switch is connected between these pins to activate these features?

Does do each of these then send a specific Gcode command to the arduino running GRBL or are these pins connected to the raspberry pi?

I looked on the wiki but there was no detailed explanation of how to use these pins.

Thanks

Abort, Hold, Resume are all linked pins that GRBL checks and acts on. No G-Code involved and part of GRBL code.

E-STOP is the emergency stop that reset the Microcontroller.,

Abort, Hold, Resume gets activated when connected to ground.
