NMI Control (NMI) – Offset 3330
Bit Range | Default | Access | Field Name and Description |
---|---|---|---|
30:5 | - | - | Reserved
|
4 | 0b | RO/V | NMI Status (NMI_STS) RO status bit indicating the current NMI status. The bit will be set to (1b1) if any NMI source is asserted and NMI2SMI_EN is set to (1b0). |
3 | 0b | RO/V | NMI-to-SMI Status (NMI2SMI_STS) RO status bit indicating the current NMI2SMI status. The bit will be set (1b1) if any NMI source is asserted and NMI2SMI_EN is set (1b1). |
2 | 0b | RW | NMI-to-SMI Enable (NMI2SMI_EN) Setting to 1b1 causes NMIs to be sent as ASSERT_SMI/DEASSERT_SMI messages to PMC instead of the regular NMI messages. Setting to 1b0 maintains the regular NMI routing (as VLW and VM).Bits NMI_NOW and NMI2SMI_EN can't be configurated on same cycle. |
1 | 0b | RO/V | NMI NOW Status (NMI_NOW_STS) RO status bit indicating the current state of NMI_NOW. See NMI_NOW. |
0 | 0b | WO | NMI Now Command (NMI_NOW) Writing 1b1 to NMI_NOW inverts the NMI NOW Status (NMI_NOW_STS) value. The first time NMI_NOW is written sets the NMI_NOW_STS and initiates an NMI. The next write clears the NMI_NOW_STS and allows initiating NMI by the next write to NMI_NOW. Writing 1b0 to NMI_NOW has no effect.Bits NMI_NOW and NMI2SMI_EN can't be configurated on same cycle. |
