Performance Monitor Reset Interrupt. Active-high
signal indicating a 1 second event has occurred.
This bit is COR/W.
Reserved. These bits must be written to their reset
default value (000).
General-Purpose Interrupt. Signal indicating the
associated input is active. When the GPIO are out-
puts, this signal will be forced low. These interrupts
are COR/W when the interrupt is programmed to
the positive edge mode; otherwise, this is a read-
only (RO) location.
UTOPIA Composite Interrupt. Active-high signal
indicating an unmasked delta or event is active in
the UTOPIA block. This bit is RO.
Data Engine Composite Interrupt. Active-high
signal indicating an unmasked delta or event is
active in the data engine block. This bit is RO.
Reserved. These bits must be written to their reset
default value (0000).
Path Terminator Composite Interrupt. Active-high
signal indicating an unmasked delta or event is
active in the path terminator block. This bit is RO.
Overhead Processor Composite Interrupt.
Active-high signal indicating an unmasked delta or
event is active in the overhead processor block.
This bit is RO.
Reserved. These bits must be written to their reset
default value (0x000).
