The eFUSEs can be programmed by system software running on an RPU or APU processor or via the PJTAG interface (on MIO) that connects to the Arm DAP controller and becomes an AXI bus master. In both cases, the eFUSE programming registers are accessed.

The XilSKey macro library provides a convenient structure to program the eFUSEs. For details on eFUSE programming, see the Programming BBRAM and eFUSEs Application Note (XAPP1319) [Ref 20].
