6.1 HOST_IRQ Usage Model
In the DLPC23x-Q1, the Host_IRQ signal is used to serve as an indication that a serious system error has occurred for which the ASIC has executed an emergency shutdown. The specific errors that precipitated the shutdown can be retrieved through the Host Command and Control interface. The actions that are taken by the ASIC for an emergency shutdown are:
- LEDs are disabled.
- The DMD is parked and powered-down.
- The ASIC operational mode is transitioned to Standby.
- The precipitating errors are captured for later review.
- The Host_IRQ signal is set to a high state.
To recover from an emergency shutdown, the system will require a full power cycle (deassertion of PROJ_ON). The host must obtain the error history from the ASIC prior to this full reset, as the reset will remove all error history from the system.
