Hawk Internal Error Interrupt Vector/Priority Register
MASK MASK. Setting this bit disables any further inte rrupts
from this source. If the mask bit is cleared, w hile 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 one when its associated bit in the Interrupt Pending
Register or In-Service Register is set.
SENSE SENSE. This bit sets the sense for Hawk’s internal error
interrupt. It is hardwired to 1 to enable activ e lo w level
sensitive interrupts.
PRIOR PRIORITY. Interrupt priority 0 is the lowest and 15 is
the highest. Note that a priority level of 0 will no t enable
interrupts.
VECTOR VECTOR. This vector is returned when the Interrupt
Acknowledge register is examined upon acknowledgment
of the interrupt associated with this vector.
