Table 4-3. Registers Read by Interrupt Controller
Name
System control register
IRQ sense control register
IRQ enable register
(1) System Control Register (SYSCR)—H’FFC4
Bit 2 (NMIEG) is the only bit read by the interrupt controller.
Bit 2—Nonmaskable Interrupt Edge (NMIEG): Determines whether a nonmaskable interrupt is
generated on the falling or rising edge of the NMI input signal.
