Normal Interrupt Pending Register (Nipnd; Fast Interrupt Pending Register (Fipnd; Normal Interrupt Pending Register; Fast Interrupt Pending Register - Motorola M-CORE MMC2001 Series Reference Manual

When the enable flag is set and the corresponding interrupt line is asserted, the inter-
rupt controller asserts a fast interrupt request. Enabling an interrupt source that has
an asserted request causes that interrupt to become pending, and a request to the
CPU is asserted if not already outstanding.

NPx — Normal Interrupt Pending Flag x
This bit indicates a pending normal interrupt request from the corresponding interrupt
source.
0 = No request
1 = Interrupt request pending
When a normal interrupt enable flag is set and the corresponding interrupt line is
asserted, the interrupt controller asserts a normal interrupt request. The normal inter-
rupt pending flags reflect the interrupt input lines which are asserted and are currently
enabled to generate a normal interrupt.
C.2.5 Fast Interrupt Pending Register (FIPND)
Access the 32-bit read-only fast interrupt pending register with 32-bit loads only.
