Register 11: Interrupt 32-47 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

Reset Description
0x000
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.
0x0.0000 Interrupt Clear Pending
Value Description
0 On a read, indicates that the interrupt is not pending.
On a write, no effect.
1 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.
