Device Interrupt Moderation Register
| DEVICE_IMODI | Moderation Interval. This bit field holds the minimum inter-interrupt interval between events. The interval is specified in terms of 250-ns increments. A value of 0 disables the interrupt throttling logic and interrupts are generated immediately if event count becomes non-zero. In scaledown simulation mode, 4 RAM clocks are used to time 250 ns. |
| DEVICE_IMODC | Interrupt Moderation Down Counter. Loaded with the DEVICE_IMODI value, whenever the hardware interrupt(n) line is de-asserted from the asserted state, counts down to 0, and stops. The interrupt is signaled whenever this counter is 0, the GEVNTCOUNT0[EVNT_HANDLER_BUSY] bit is 0x0, and there are pending events (that is, event count is non-zero). This counter may be directly written by software at any time to alter the interrupt rate. |
