Register 16: Interrupt 0-31 Clear Pending (UNPEND0), offset 0x280
Register 17: Interrupt 32-63 Clear Pending (UNPEND1), offset 0x284
Register 18: Interrupt 64-95 Clear Pending (UNPEND2), offset 0x288
Register 19: Interrupt 96-113 Clear Pending (UNPEND3), offset 0x28C
Note: This register can only be accessed from privileged mode.
The UNPENDn registers show which interrupts are pending and remove the pending state from
interrupts. Bit 0 of UNPEND0 corresponds to Interrupt 0; bit 31 corresponds to Interrupt 31. Bit 0 of
UNPEND1 corresponds to Interrupt 32; bit 31 corresponds to Interrupt 63. Bit 0 of UNPEND2
corresponds to Interrupt 64; bit 31 corresponds to Interrupt 95. Bit 0 of UNPEND3 corresponds to
Interrupt 96; bit 31 corresponds to Interrupt 113.
See Table 2-9 on page 125 for interrupt assignments.

Interrupt Clear Pending
DescriptionValue
On a read, indicates that the interrupt is not pending.
On a write, no effect.
0
On a read, indicates that the interrupt is pending.
On a write, clears the corresponding INT[n] bit in the PEND0
register, so that interrupt [n] is no longer pending.
Setting a bit does not affect the active state of the corresponding
interrupt.
