INT2A1 is a 32-bit read-only register that indicates the interrupt sources of on-chip peripheral
modules. If an interrupt is masked by the interrupt mask register, the corresponding bit in INT2A1
is not set to 1. Use INT2A0 to check whether interrupts have been generated, regardless of the
state of the interrupt mask register.
Table 10.8 shows the correspondence between bits in INT2A1 and the interrupt sources.

Description
These bits indicate the interrupt
source of each peripheral module
that is generating an interrupt.
(INT2A1 is 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.
