Interrupt Request Map
pipeline stall, which prevents the interrupt from accidentally re-triggering in case the handler is
exited and the interrupt mask is cleared before the interrupt request is cleared.
This chapter lists the INTC registers are accessible through the PB bus. The registers are used
to control the behaviour and read the status of the INTC.
The following table shows the address map of the INTC registers, relative to the base address of
the INTC.
Table 16-1.
The mapping of interrupt requests from peripherals to INTREQs is presented in the Peripherals
Section.
