Value
Description
31:23 Read
only
0 Always read as 0.
22:7 Read
only
0 IRQBASE register value.
6:2 Read
only
0 Highest priority IRQ source. This
is a value between 0 to 19 repre-
senting the possible interrupt
sources. For example, if the highest
currently active IRQ is Timer1, then
these bits are [01000].

0
Reserved bits.
Priority Registers
The interrupt priority registers, IRQP0, IRQP1, and IRQP2,
allow each interrupt source to have its priority level configured
for a level between 0 and 7. Level 0 is the highest priority level.
