The ICDICFR1 register is read-only, since it specifies the sensitivity types of all five PPIs.

The fast interrupt (FIQ) signal and the interrupt (IRQ) signal from the PL are inverted and then sent to the interrupt controller. Consequently, they are active High at the PS-PL interface, although the ICDICFR1 register reflects them as active Low level.
