Table 10-39
10.3.7
The interrupt source configuration registers control the source of each interrupt, specifying parameters
such as the interrupting event, signal polarity, and relative priority.
10.3.7.1
The external interrupt vector/priority registers (EIVPRs) contain polarity and sense fields for the external
interrupts caused by the assertion of any of IRQ[0:11]. The format of the EIVPRs is shown in

Reserved.
Processor 0. Set to 1 directs the interrupt to processor 0.
Mask. Masks interrupts from this source.
0 If the corresponding IPR bit is set an interrupt request is generated.
1 Interrupts from this source are disabled.
Activity. A read-only field indicating that an interrupt has been requested or is in-service. Note: The P
(polarity), S (sense), VECTOR and PRIORITY values should not be changed while the corresponding
interrupt is active, that is, while EIVPR n [A] is set.
0 No current interrupt activity associated with this source.
1 The interrupt bit for this source is set in the IPR or ISR.
Reserved.
Polarity. Specifies the polarity for the external interrupt.
0 Polarity is active-low or negative edge triggered.
1 Polarity is active-high or positive edge-triggered.
Sense. Specifies the sense for external interrupts.
0 The external interrupt is edge sensitive.
1 The external interrupt is level-sensitive.
