Bit Range | Default | Access | Field Name and Description |
---|---|---|---|
31:16 | 0000h | RW | Interrupt Moderation Counter (IMODC) Down counter. Loaded with Interval Moderation value—value of bits 15:0, whenever the IP bit is cleared to 0b, counts down to ‘0’, and stops. The associated interrupt shall be signaled whenever this counter is ‘0’, the Event Ring is not empty, the IE and IP bits = 1, and EHB = 0.This counter may be directly written by software at any time to alter the interrupt rate |
15:0 | 0FA0h | RW | Interrupt Moderation Interval (IMODI) Minimum inter-interrupt interval. The interval is specified in 250 ns increments. A value of ‘0’ disables interrupt throttling logic and interrupts shall be generated immediately if IP = 0, EHB = 0, and the Event Ring is not empty. |
