How to acknowledge interrupts on AD9371?

Question asked by tcachat on Jul 5, 2018

In the documentation, page 226/360, I read:

"Note that the phase-locked loop (PLL) unlock bits are not sticky. These bits follow the current status of the PLLs. If the PLL relocks, the status bit clears as well."

I understand for the PLL unlock bits, but I suppose it means also that the other bits are sticky. How can one acknowledge the other bits?

Currently bit 5 (JESD204 deframer interrupt occurred) is set, which is consistent with the DeframerStatus where bit 6 (This bit indicates that the IRQ interrupt was asserted). How to acknoledge?
