Raven-Detected Errors Vector/Priority Register
MASK MASK. Setting this bit disables any further interrupts from this
source. If the mask bit is cleared while the bit associated with this interrupt
is set in the IPR, the interrupt request will be generated.
ACT ACTIVITY. The activity bit indicates that an interrupt has been
requested or that it is in-service. The ACT bit is set to a one when its
associated bit in the Interrupt Pending Register or In-Service Register is
set.
SENSE SENSE. This bit sets the sense for the internal Raven Detected
Errors interrupt. This bit is hardwired to 1 to enable active low level
sensitive interrupts.
PRIOR Interrupt priority 0 is the lowest and 15 is the highest. Note that
a priority level of 0 will not enable interrupts.
VECTOR This vector is returned when the Interrupt Acknowledge
register is examined upon acknowledgedment of the interrupt associated
with this vector.
