Document Table of Contents ACTIVE_ENGAGE

The ACTIVE_ENGAGE instruction allows you to re-engage a disengaged active controller.
You can issue this instruction any time during configuration or user mode to reengage an already disengaged active controller, as well as trigger reconfiguration of the Intel® Cyclone® 10 LP device in the active configuration scheme. The ACTIVE_ENGAGE instruction functions as the PULSE_NCONFIG instruction when the device is in the PS or FPP configuration schemes. The nCONFIG pin is disabled when the ACTIVE_ENGAGE instruction is issued.
Note: Intel does not recommend using the ACTIVE_ENGAGE instruction, but it is provided as a fail-safe instruction for re-engaging the active configuration controller (AS).
