10.3.10 Interrupt Source Register (INT2A0: Not affected by Mask States)
INT2A0 is a 32-bit read-only register that indicates interrupt states of interrupt source modules
regardless of the corresponding mask states. Even if interrupt masking is set in the interrupt mask
register, corresponding bits in INT2A0 indicate source modules for which interrupt conditions
have been satisfied (the corresponding interrupt is not generated). When sources that are masked
should not be indicated, use INT2A1.
Table 10.6 shows the correspondence between bits in INT2A0 and sources.
