No software-encoding of end-positions, its in the hardware of their trinamic drivers, the so called "StallGuard" technologiy. If the motor-movement is stopped by a physical barrier, the current-flow changes significantly, which is detected by the trinamic-chip-based driver. See https://www.trinamic.com/technology/adv-technologies/stallguard/

These drivers once have been btw. part of a crowdfunding campaign at indiegogo featuring a beaglebone-compatible cape named "T-Bone", see https://www.indiegogo.com/projects/t-bone-cape-for-diy-3d-printing-with-beaglebone#/ I just mention that because it means that this can act as an opensource reference-design.
