[30:0] Interrupt Mode Bit
Each of the 31bits in the interrupt mode
register, INTMOD, corresponds to an interrupt source. When
the source's interrupt mode bit is set to '1', the interrupt is
processed by the ARM7TDMI core in FIQ (fast interrupt)
mode. Otherwise, it is processed in IRQ mode (normal
interrupt).
The 30 interrupt sourcess are summarized in Table 15-1.
