General Purpose Event 1 Status [63:32] (GPE1_STS_63_32) – Offset 14
Note: This register is symmetrical to the General Purpose Event 0 Enable [127:96] Register. Unless indicated otherwise below, if the corresponding _EN bit is set, then when the STS bit get set, the processor will generate a Wake Event. Once back in an S0 state (or if already in an S0 state when the event occurs), the processor will also generate an SCI if the SCIEN bit is set, or an SMI# if the SCIEN bit is not set and GBL_SMI_EN is set.
Note that GPE0_STS bits 95:0 are claimed by the GPIO register block.
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 31:14 | 0h | RO | Reserved |
| 13 | 0h | RW/1C/V | TC_TBT1 Hot Plug Status (TC_TBT1_HOT_PLUG_STS) This bit is set to 1 by hardware when a PCIE_HOTPLUG_MSG(TC_TBT1) event occurs. This will cause an SCI if the TC_TBT1_HOT_PLUG_EN and SCI_EN bits are set. This bit is cleared by writing a 1 to this bit position. The following events cause this bit to set |
| 12 | 0h | RW/1C/V | TC_TBT0 Hot Plug Status (TC_TBT0_HOT_PLUG_STS) This bit is set to 1 by hardware when a PCIE_HOTPLUG_MSG(TC_TBT0) event occurs. This will cause an SCI if the TC_TBT0_HOT_PLUG_EN and SCI_EN bits are set. This bit is cleared by writing a 1 to this bit position. The following events cause this bit to set |
| 11 | 0h | RW/1C/V | TC_PCIE3 Hot Plug Status (TC_PCIE3_HOT_PLUG_STS) This bit is set to 1 by hardware when a PCIE_HOTPLUG_MSG(TC_PCIE3) event occurs. This will cause an SCI if the TC_PCIE3_HOT_PLUG_EN and SCI_EN bits are set. This bit is cleared by writing a 1 to this bit position. The following events cause this bit to set |
| 10 | 0h | RW/1C/V | TC_PCIE2 Hot Plug Status (TC_PCIE2_HOT_PLUG_STS) This bit is set to 1 by hardware when a PCIE_HOTPLUG_MSG(TC_PCIE2) event occurs. This will cause an SCI if the TC_PCIE2_HOT_PLUG_EN and SCI_EN bits are set. This bit is cleared by writing a 1 to this bit position. The following events cause this bit to set |
| 9 | 0h | RW/1C/V | TC_PCIE1 Hot Plug Status (TC_PCIE1_HOT_PLUG_STS) This bit is set to 1 by hardware when a PCIE_HOTPLUG_MSG(TC_PCIE1) event occurs. This will cause an SCI if the TC_PCIE1_HOT_PLUG_EN and SCI_EN bits are set. This bit is cleared by writing a 1 to this bit position. The following events cause this bit to set |
| 8 | 0h | RW/1C/V | TC_PCIE0 Hot Plug Status (TC_PCIE0_HOT_PLUG_STS) This bit is set to 1 by hardware when a PCIE_HOTPLUG_MSG(TC_PCIE0) event occurs. This will cause an SCI if the TC_PCIE0_HOT_PLUG_EN and SCI_EN bits are set. This bit is cleared by writing a 1 to this bit position. The following events cause this bit to set |
| 7 | 0h | RW/1C/V | IOE Hot Plug Status (IOE_HOT_PLUG_STS) Enables SCI when the IOE_HOT_PLUG_STS bit is set. This is used to allow the PCI Express ports to cause an SCI due to hot-plug events. |
| 6:2 | 0h | RO | Reserved |
| 1 | 0h | RW/1C/V | SPB Hot Plug Status (SPB_HOT_PLUG_STS) Enables SCI when the SPB_HOT_PLUG_STS bit is set. This is used to allow the PCI Express ports to cause an SCI due to hot-plug events. |
| 0 | 0h | RW/1C/V | SPA Hot Plug Status (SPA_HOT_PLUG_STS) Enables SCI when the SPA_HOT_PLUG_STS bit is set. This is used to allow the PCI Express ports to cause an SCI due to hot-plug events. |
