Handshaking with processor

18.6.3.1

Software vector mode handshaking

This section describes handshaking in software vector mode.

18.6.3.1.1

Acknowledging interrupt request to processor

A timing diagram of the interrupt request and acknowledge handshaking in software vector mode, along 
with the handshaking near the end of the interrupt exception handler, is shown in 

Figure 18-11

. The INTC 

examines the peripheral and software configurable interrupt requests. When it finds an asserted peripheral 
or software configurable interrupt request with a higher priority than PRI in the associated INTC_CPR, it 
asserts the interrupt request to the processor. The INTVEC field in the associated INTC_IACKR is updated 
with the preempting interrupt request’s vector when the interrupt request to the processor is asserted. The 
INTVEC field retains that value until the next time the interrupt request to the processor is asserted. The 
rest of the handshaking is described in 

Section 18.4.1.1, Software vector mode

.

18.6.3.1.2

End of interrupt exception handler

Before the interrupt exception handling completes, INTC end-of-interrupt register (INTC_EOIR) must be 
written.When written, the associated LIFO is popped so the preempted priority is restored into PRI of the 
INTC_CPR. Before it is written, the peripheral or software configurable flag bit must be cleared so that 
the peripheral or software configurable interrupt request is negated.

NOTE

To ensure proper operation across all Power Architecture MCUs, execute an 

MBAR 

or 

MSYNC 

instruction between the access to clear the flag bit and the 

write to the INTC_EOIR.

When returning from the preemption, the INTC does not search for the peripheral or software settable 
interrupt request whose ISR was preempted. Depending on how much the ISR progressed, that interrupt 
request may no longer even be asserted. When PRI in INTC_CPR is lowered to the priority of the 
preempted ISR, the interrupt request for the preempted ISR or any other asserted peripheral or software 
settable interrupt request at or below that priority will not cause a preemption. Instead, after the restoration 
of the preempted context, the processor will return to the instruction address that it was to next execute 
before it was preempted. This next instruction is part of the preempted ISR or the interrupt exception 
handler’s prolog or epilog.
