18.1.1 VIC Interrupt Listing
Table 18-1 lists the 32 interrupt source lines for the VIC and their permanent position
assignment. For a detailed description of each interrupt, see the chapter for the peripheral
that generates the interrupt
.
NOTE: *All interrupts are available in RUN Mode. If an interrupt not marked with a bullet wakes the SoC
unintentionally, the offending interrupt should be disabled in the VIC.
