Functional Description
10.4.1
Interrupt Request Sources
The INTC has two types of interrupt requests, peripheral and software settable. The assignments between
the interrupt requests from the modules to the vectors for input to the e200z6 are shown in
. The
Hardware Vector Mode Offset column lists the IRQ-specific offsets when using hardware vector mode.
The Source column shows the C language syntax for the register bit label: module_register[bit]. Interrupt
requests from the same module location are ORed together. The individual interrupt priorities are selected
in INTC_PSR
n
, where the priority select register is assigned according to the vector number.
