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.

Description
On a read, indicates that the interrupt is not pending.
On a write, no effect.
On a read, indicates that the interrupt is pending.
On a write, the corresponding interrupt is set to pending
even if it is disabled.
If the corresponding interrupt is already pending, setting a bit has no
effect.
A bit can only be cleared by setting the corresponding INT[n] bit in
the UNPEND0 register.
