|
| 10 | 0b | RW | Interrupt Disable (ID) Enables the device to assert an INTx#. When set, the Thermal logics INTx# signal will be de-asserted. When cleared AND MSI is not enabled, the INTx# signal may be asserted. NOTE: this bit has no affect on MSI generation. |
| 9 | 0b | RO | Fast Back to Back Enable (FBE) Not implemented. Hardwired to 0. |
| 8 | 0b | RW | SERR Enable (SEN) When set to 1 and an error occurs, SERR# is signaled to the system. |
| 7 | 0b | RO | Wait Cycle Control (WCC) Not implemented. Hardwired to 0. |
| 6 | 0b | RO | Parity Error Response (PER) Not implemented. Hardwired to 0. |
| 5 | 0b | RO | VGA Palette Snoop (VPS) Not implemented. Hardwired to 0. |
| 4 | 0b | RO | Memory Write and Invalidate Enable (MWI) Not implemented. Hardwired to 0. |
| 3 | 0b | RO | Special Cycle Enable (SCE) Not implemented. Hardwired to 0. |
| 2 | 0b | RW | Bus Master Enable (BME) When 1, enables |
| 1 | 0b | RW | Memory Space Enable (MSE) When set, enables memory space accesses to the Thermal registers. |
| 0 | 0b | RO | I/O Space (IOS) The Thermal logic does not implement IO Space, therefore this bit is hardwired to 0. |
