6.3.2 Device Startup

  • The HOST_IRQ signal is provided to indicate when the system has completed auto-initialization.
  • While reset is applied, HOST_IRQ is tristated (an external pullup resistor pulls the line high).
  • HOST_IRQ remains tristated (pulled high externally) until the boot process completes. While the signal is pulled high, this indicates that the controller is performing boot-up and auto-initialization.
  • As soon as possible after the controller boots up, the controller drives HOST_IRQ to a logic high state to indicate that the controller is continuing to perform auto-initialization (no real state changes occur on the external signal).
  • The software sets HOST_IRQ to a logic-low state at the completion of the auto-initialization process. At the falling edge of the signal, the initialization is complete.
  • The DLPC34x6 controller is ready to receive commands through I2C or accept video over the parallel interface only after auto-initialization is complete.
  • The controller initialization typically completes (HOST_IRQ goes low) within 2.94s of RESETZ being asserted. However, this time may vary (typically up to 0.3s) depending on the software version and the contents of the user-configurable auto-initialization file.
DLPC3436 HOST_IRQ Timing
t0: rising edge of RESETZ; auto-initialization begins.
t1: falling edge of HOST_IRQ; auto-initialization is complete.
