Interrupt Source Register (Not affected by Mask Setting) (INT2A0)
INT2A0 is a 32-bit read-only register that indicates the interrupt sources of on-chip peripheral
modules. Even if an interrupt is masked by the interrupt mask register, the corresponding bit in
INT2A0 is set (further interrupt operation is not performed for the corresponding bit). Use
INT2A1 instead if the bits for the interrupt sources masked by the interrupt mask registers should
not be set.

These bits indicate the
interrupt source of each
peripheral module that is
generating an interrupt.
(INT2A0 is not affected by the
setting of the interrupt mask
register).
0: No interrupt
1: An interrupt has occurred
Note: Interrupt sources can
also be identified by
directly reading the
INTEVT code. In this
case, reading from this
register is not required.
