than the earlier portion of the ISR but do have a higher priority than what the later portion of the ISR needs. 
This preemptive scheduling inefficiency reduces the processor's ability to meet its deadlines.

One option is for the ISR to complete the earlier higher priority portion, but then schedule through the 
RTOS a task to execute the later lower priority portion. However, some RTOSs can require a large amount 
of time for an ISR to schedule a task. Therefore, a second option is for the ISR, after completing the higher 
priority portion, to set a SET

n 

bit in INTC software set/clear interrupt registers 

(INTC_SSCIR0–INTC_SSCIR7). Writing a 1 to SET

n

 causes a software settable interrupt request. This 

software settable interrupt request, which usually has a lower PRI

n

 value in the INTC_PSR

n

, therefore 

does not cause preemptive scheduling inefficiencies.

After generating a software settable interrupt request, the higher priority ISR completes. The lower priority 
ISR is scheduled according to its priority. Execution of the higher priority ISR is not resumed after the 
completion of the lower priority ISR.

10.5.7.2

Scheduling an ISR on Another Processor

Since the SET

n

 bits in the INTC_SSCIR

n

 are memory mapped, processors in multiple processor systems 

can schedule ISRs on the other processors. One application is that one processor simply wants to command 
another processor to perform a piece of work, and the initiating processor does not need to use the results 
of that work. If the initiating processor is concerned that processor executing the software settable ISR has 
not completed the work before asking it to again execute that ISR, it can check if the corresponding CLR

n

 

bit in INTC_SSCIR

n

 is asserted before again writing a 1 to the SET

n

 bit.

Another application is the sharing of a block of data. For example, a first processor has completed 
accessing a block of data and wants a second processor to then access it. Furthermore, after the second 
processor has completed accessing the block of data, the first processor again wants to access it. The 
accesses to the block of data must be done coherently. The procedure is that the first processor writes a 1 
to a SET

n

 bit on the second processor. The second processor, after accessing the block of data, clears the 

corresponding CLR

n

 bit and then writes 1 to a SET

n

 bit on the first processor, informing it that it now can 

access the block of data.

10.5.8

Lowering Priority Within an ISR

In implementations without the software-settable interrupt requests in the INTC software set/clear 
interrupt registers (INTC_SSCIR0–INTC_SSCIR7), a way — besides scheduling a task through an RTOS 
— to prevent preemptive scheduling inefficiencies with an ISR whose work spans multiple priorities (as 
described in 

Section 10.5.7.1, “Scheduling a Lower Priority Portion of an ISR

,”) is to lower the current 

priority. However, the INTC has a LIFO whose depth is determined by the number of priorities.

NOTE

Lowering the PRI value in INTC current priority register (INTC_CPR) 
within an ISR to below the ISR’s corresponding PRI value in INTC priority 
select registers (INTC_PSR0–INTC_PSR231) allows more preemptions 
than the depth of the LIFO can support.

Therefore, through its use of the LIFO the INTC does not support lowering the current priority within an 
ISR as a way to avoid preemptive scheduling inefficiencies.
