This register contains the maximum latency, minumum grand, interrupt pin and interrupt level registers.
Bit Range | Default | Access | Field Name and Description |
---|---|---|---|
31:24 | 00h | RO | Maximum Latency (MAXL) Not implemented. Hardwired to 0. |
23:16 | 00h | RO | Minimum Grant (MING) Not implemented. Hardwired to 0. |
15:8 | 00h | RO/V | Interrupt Pin (INTP) This register specifies which interrupt pin IDE uses in PCI interrupt mode. |
7:0 | 00h | RW | Interrupt Line (INTL) The value written in this register indicates which input of thesystem interrupt controller, the device's interrupt pin is connected to. This value is used by theoperating system and the device driver, and has no affect on the hardware |
