Overrun Request Enable Register (SIU_ORER)
The SIU_ORER contains bits to enable an overrun if the corresponding flag bit is set in the SIU_OSR. If
the overrun request enable bit and the flag bit are set, the single combined overrun request from the SIU
to the interrupt controller is asserted.
The following table describes the fields in the overrun request enable register:

Overrun request enable
n. E
nables the overrun request when an overrun occurs on the IRQ[
n
] pin. Bit 31 (ORE0) is
the enable overrun flag for IRQ[0]; bit 16 (ORE15) is overrun flag for IRQ[15].
0 Overrun request is disabled.
1 Overrun request is enabled.
