10.4 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 Table 10-9. The
Offset column lists the IRQ specific offsets when using hardware vector mode. The Source column is
written in C language syntax. The syntax is ‘module_register[bit].’ Interrupt requests from the same
module location are ORed together. The individual interrupt priorities are selected in INTC_PSRn, where
the specific select register is assigned according to the vector.
