The INTC has 10 internal channels to which enabled interrupts can be mapped. Channel 0 has highest priority and channel 9 has the lowest priority. Channels are used to group the interrupts into a smaller number of priorities that can be given to a host interface with a very small number of interrupt inputs.
When multiple interrupts are mapped to the same channel their interrupts are ORed together so that when either is active the output is active. The channel map registers (ICSS_INTC_CH_MAP_REGi) define the channel for each interrupt. There is one register per 4 interrupts; therefore, there are 16 channel map registers for a of 64 interrupts. The channel for each interrupt can be set using these registers.
