The hosts can be the local PRU processors (PRU0 and PRU1) as well as device processors located outside PRU-ICSS such as ARM, etc. The 10 channels from the INTC can be mapped to any of the 10 Host interrupts. The Host map registers (ICSS_INTC_HINT_MAP_REG0 to ICSS_INTC_HINT_MAP_REG4) define the channel for each interrupt. There is one register per 4 channels; therefore, there are 3 host map registers for 10 channels. When multiple channels are mapped to the same host interrupt, then prioritization is done to select which interrupt is in the highest-priority channel and which should be sent first to the host.
