Interrupt Request Signal Map
Table 10-2.
The various modules may output Interrupt request signals. These signals are routed to the Inter-
rupt Controller (INTC), described in a later chapter. The Interrupt Controller supports up to 64
groups of interrupt requests. Each group can have up to 32 interrupt request signals. All interrupt
signals in the same group share the same autovector address and priority level. Refer to the
documentation for the individual submodules for a description of the semantics of the different
interrupt requests.
The interrupt request signals are connected to the INTC as follows.
