Interrupts
Interrupt Latch Register (IRPTL)
The IRPTL register is a non-memory-mapped, universal, system register
(Ureg and Sreg). The reset value for this register is 0x0000 0000. The
IRPTL register indicates latch status for interrupts. Figure B-3, Figure B-4
and Table B-5 provide bit definitions for the IRPTL register.
