Pad Configuration DW0 (PAD_CFG_DW0_xxgpp_h_6) – Offset 800
Same description as PAD_CFG_DW0_xxgpp_h_0.
Note: The register is reserved if the corresponding GPIO is not available.
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 31:30 | 1h | RW | Pad Reset Config (PADRSTCFG) Same description as RXTXENCFG bit in PAD_CFG_DW0_xxgpp_h_0 register. |
| 29 | 0h | RW | RX Pad State Select (RXPADSTSEL) Same description as RXRAW1 bit in PAD_CFG_DW0_xxgpp_h_0 register. |
| 28 | 0h | RW | RX Raw Override to '1' (RXRAW1) Same description as RXPADSTSEL bit in PAD_CFG_DW0_xxgpp_h_0 register. |
| 27 | 0h | RO | Native Function Virtual Wire Message Enable (NAF_VWE) Same description as RXINV bit in PAD_CFG_DW0_xxgpp_h_0 register. |
| 26:25 | 2h | RW | RX Level/Edge Configuration (RXEVCFG) Same description as RXEVCFG bit in PAD_CFG_DW0_xxgpp_h_0 register. |
| 24 | 0h | RW | Pre Glitch Filter Stage RX Pad State Select (PREGFRXSEL) Determine if the synchronized version of the raw RX pad state should be subjected to glitch filter or not. This field only makes sense when the RX buffer is configured as an input and is not disabled. 0 = Select synchronized, non filtered RX pad state 1 = Select synchronized, filtered RX pad state The selected RX pad state can be further subjected to polarity inversion through RXINV Notes: The ResetSignal is configured by Pad Reset Config (PadRstCfg) in Pad Configuration DW0 register. \t\t\t |
| 23 | 0h | RW | RX Invert (RXINV) This bit determines if the selected pad state should go through the polarity inversion stage. This field only makes sense when the RX buffer is configured as an input in either GPIO Mode or native function mode. The polarity inversion takes place at the mux node of raw vs filtered or non-filtered RX pad state, as determined by PreGfRXsel and RXPadStSel This bit does not affect GPIORXState. During host ownership GPIO Mode, when this bit is set to '1', then the RX pad state is inverted as it is sent to the GPIO-to-IOxAPIC, GPE/SCI, SMI, NMI logic or GPI_IS[n] that is using it. This is used to allow active-low and active-high inputs to cause IRQ, SMI#, SCI or NMI. 0 = No inversion 1 = Inversion Notes: The ResetSignal is configured by Pad Reset Config (PadRstCfg) in Pad Configuration DW0 register. \t\t\t |
| 22:21 | 0h | RW | RX/TX Enable Config (RXTXENCFG) Same description as PREGFRXSEL bit in PAD_CFG_DW0_xxgpp_h_0 register. |
| 20 | 0h | RW | GPIO Input Route IOxAPIC (GPIROUTIOXAPIC) Same description as PMODE bit in PAD_CFG_DW0_xxgpp_h_0 register. |
| 19 | 0h | RW | GPIO Input Route SCI (GPIROUTSCI) Same description as PADRSTCFG bit in PAD_CFG_DW0_xxgpp_h_0 register. |
| 18 | 0h | RO | GPIO Input Route SMI (GPIROUTSMI) Same description as NAF_VWE bit in PAD_CFG_DW0_xxgpp_h_0 register. |
| 17 | 0h | RO | GPIO Input Route NMI (GPIROUTNMI) Same description as GPIROUTSMI bit in PAD_CFG_DW0_xxgpp_h_0 register. |
| 16:13 | 0h | RO | Reserved (RSVD_0) Same description as GPIROUTSCI bit in PAD_CFG_DW0_xxgpp_h_0 register. |
| 12:10 | 0h | RW | Pad Mode (PMODE) Same description as GPIROUTNMI bit in PAD_CFG_DW0_xxgpp_h_0 register. |
| 9 | 1h | RW | GPIO RX Disable (GPIORXDIS) Same description as GPIROUTIOXAPIC bit in PAD_CFG_DW0_xxgpp_h_0 register. |
| 8 | 1h | RW | GPIO TX Disable (GPIOTXDIS) Same description as GPIOTXSTATE bit in PAD_CFG_DW0_xxgpp_h_0 register. |
| 7:2 | 0h | RO | Reserved (RSVD_1) Same description as GPIOTXDIS bit in PAD_CFG_DW0_xxgpp_h_0 register. |
| 1 |
| RO/V | GPIO RX State (GPIORXSTATE) Same description as GPIORXSTATE bit in PAD_CFG_DW0_xxgpp_h_0 register. |
| 0 | 0h | RW | GPIO TX State (GPIOTXSTATE) Same description as GPIORXDIS bit in PAD_CFG_DW0_xxgpp_h_0 register. |
