2.5 Device to Host Interrupts

The HIC module supports Host interrupt capability by using the HIC_INT Device output pin. Any general-purpose input I/O pin of the Host with the interrupt capability can be connected to the HIC_INT pin. There are two ways of generating interrupts from the Device through HIC_INT as described in the subsequent sections.
