| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 31 | 0h | RW/V | PG5_PMA0 PCI Express Enable 3 (PG5_PMA0_PCI_EXP_EN_3) Enables an SCI to be generated when PCI_EXP_STS bit is set. This is used to allow the PCI Express ports, to cause an SCI due to wake/PME events. |
| 30 | 0h | RW/V | PG5_PMA0 PCI Express Enable 2 (PG5_PMA0_PCI_EXP_EN_2) Enables an SCI to be generated when PCI_EXP_STS bit is set. This is used to allow the PCI Express ports, to cause an SCI due to wake/PME events. |
| 29 | 0h | RW/V | PG5_PMA0 PCI Express Enable 1 (PG5_PMA0_PCI_EXP_EN_1) Enables an SCI to be generated when PCI_EXP_STS bit is set. This is used to allow the PCI Express ports, to cause an SCI due to wake/PME events. |
| 28 | 0h | RW/V | PG5_PMA0 PCI Express Enable 0 (PG5_PMA0_PCI_EXP_EN_0) Enables an SCI to be generated when PCI_EXP_STS bit is set. This is used to allow the PCI Express ports, to cause an SCI due to wake/PME events. |
| 27 | 0h | RW/V | PG5_PMA1 PCI Express Enable 3 (PG5_PMA1_PCI_EXP_EN_3) Enables an SCI to be generated when PCI_EXP_STS bit is set. This is used to allow the PCI Express ports, to cause an SCI due to wake/PME events. |
| 26 | 0h | RW/V | PG5_PMA1 PCI Express Enable 2 (PG5_PMA1_PCI_EXP_EN_2) Enables an SCI to be generated when PCI_EXP_STS bit is set. This is used to allow the PCI Express ports, to cause an SCI due to wake/PME events. |
| 25 | 0h | RW/V | PG5_PMA1 PCI Express Enable 1 (PG5_PMA1_PCI_EXP_EN_1) Enables an SCI to be generated when PCI_EXP_STS bit is set. This is used to allow the PCI Express ports, to cause an SCI due to wake/PME events. |
| 24 | 0h | RW/V | PG5_PMA1 PCI Express Enable 0 (PG5_PMA1_PCI_EXP_EN_0) Enables an SCI to be generated when PCI_EXP_STS bit is set. This is used to allow the PCI Express ports, to cause an SCI due to wake/PME events. |
| 23:14 | 0h | RO | Reserved |
| 13 | 0h | RW/V | TC_TBT1 PCI Express Enable (TC_TBT1_PCI_EXP_EN) Enables an SCI to be generated when PCI_EXP_STS bit is set. This is used to allow the PCI Express ports, to cause an SCI due to wake/PME events. |
| 12 | 0h | RW/V | TC_TBT0 PCI Express Enable (TC_TBT0_PCI_EXP_EN) Enables an SCI to be generated when PCI_EXP_STS bit is set. This is used to allow the PCI Express ports, to cause an SCI due to wake/PME events. |
| 11 | 0h | RW/V | TC_PCIE3 PCI Express Enable (TC_PCIE3_PCI_EXP_EN) Enables an SCI to be generated when PCI_EXP_STS bit is set. This is used to allow the PCI Express ports, to cause an SCI due to wake/PME events. |
| 10 | 0h | RW/V | TC_PCIE2 PCI Express Enable (TC_PCIE2_PCI_EXP_EN) Enables an SCI to be generated when PCI_EXP_STS bit is set. This is used to allow the PCI Express ports, to cause an SCI due to wake/PME events. |
| 9 | 0h | RW/V | TC_PCIE1 PCI Express Enable (TC_PCIE1_PCI_EXP_EN) Enables an SCI to be generated when PCI_EXP_STS bit is set. This is used to allow the PCI Express ports, to cause an SCI due to wake/PME events. |
