7.1.2 HOST_IRQ

For more urgent error conditions, the DLPC230S-Q1 has the HOST_IRQ signal that can be used for interrupt driven programming of the host MCU. The DLPC230S-Q1 asserts this signal high to indicate to the host MCU that a serious system error has occurred. A serious system error is something that TI considers likely to corrupt the display image, and/or create a bright display image, and/or damage one or more chipset devices. This signal can be used to interrupt the host MCU to handle the urgent error.
