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 1 when its associated bit in the Interrupt Pending
register or In-Service register is set.
SENSE Sense. This bit sets the sense for external interrupts.
Setting this bit to a 0 enables positive edge sensitive
interrupts. Setting this bit to a 1 enables active low level
sensitive interrupts.
PRIOR Interrupt Priority. Priority 0 is the lowest and 15 is the
highest. Note that a priority level of 0 will not enable
interrupts.
VECTOR Interrupt Vector. This vector is returned when the
Interrupt Acknowledge register is examined upon
acknowledgment of the interrupt associated with this
vector.
