Description
Disable the selected interrupt (no priority).
01
Enable the selected interrupt at priority 1 (lowest).
10
Enable the selected interrupt at priority 2.
11
Enable the selected interrupt at priority 3 (highest).
Reset clears all fields to disable all interrupts.

Description

Reserved—write with zero.
Read—corresponding interrupt not pending.
Write—no effect.
1
Read—corresponding interrupt is pending.
Write—clears bit and changes corresponding interrupt status to not pending
.
The core clears an interrupt’s
ins
bit if it services that interrupt. For interrupt polling, an instruction can explicitly clear an interrupt’s
ins
bit by writing a 1
to that bit and a 0 to all other
ins
bits. Writing a 0 to any
ins
bit leaves the bit unchanged.
To clear an interrupt’s status, an application writes a 1 to the corresponding bit.
