Register 11: Interrupt 32-43 Clear Pending (UNPEND1), offset 0x284
Note: This register can only be accessed from privileged mode.
The UNPEND1 register shows which interrupts are pending and removes the pending state from
interrupts. Bit 0 corresponds to Interrupt 32; bit 11 corresponds to Interrupt 43. See Table
2-9 on page 86 for interrupt assignments.

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

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 PEND1
register, so that interrupt [n] is no longer pending.
Setting a bit does not affect the active state of the corresponding
interrupt.
