Bits 5, 3(1) I[1:0]: Software interrupt priority bits(2)
These two bits indicate the software priority of the current interrupt request. When an interrupt
request occurs, the software priority of the corresponding vector is loaded automatically from the
software priority registers (ITC_SPRx).
The I[1:0] bits can be also set/cleared by software using the RIM, SIM, HALT, WFI, IRET or
PUSH/POP instructions (see Figure 9: Nested interrupt management).
