Section 9 Interrupt Controller (INTC)
9.3.14
INT2A0 (mask state is not affected) is a 32-bit read-only register that indicates interrupt source
modules. Even if interrupt masking is set in the interrupt mask register, INT2A0 indicates a source
module in a corresponding bit (the corresponding interrupt is not generated). If source indication is
not necessary depending on the state of the interrupt mask register, use INT2A1.
