| 22 | PADCONFIG33_ISO_OVR_PROXY | R/W | 0h | Isolation Override 0 - IO isolation is preserved 1 - IO isolation is overridden Reset Source: mod_por_rst_n |
| 21 | PADCONFIG33_TX_DIS_PROXY | R/W | 0h | Driver Disable 0 - Driver is enabled 1 - Driver is disabled Reset Source: mod_por_rst_n |
| 20:19 | PADCONFIG33_DRV_STR_PROXY | R/W | 0h | Drive Strength Control . Selects the drive strength value for LVCMOS pins. (Does not apply to other pin types) Reset Source: mod_por_rst_n |
| 18 | PADCONFIG33_RXACTIVE_PROXY | R/W | 0h | Input enable for the Pad 0 - Receiver disabled 1 - Receiver enabled Reset Source: mod_por_rst_n |
| 17 | PADCONFIG33_PULLTYPESEL_PROXY | R/W | 0h | Pad Pullup / Pulldown type selection 0 - Pulldown selected 1 - Pullup selected Reset Source: mod_por_rst_n |
| 16 | PADCONFIG33_PULLUDEN_PROXY | R/W | 1h | Pad Pullup / Pulldown enable. This is an active low signal. 0 - Pullup / Pulldown enabled 1 - Pullup / Pulldown disabled Reset Source: mod_por_rst_n |
| 14 | PADCONFIG33_ST_EN_PROXY | R/W | 1h | Receiver Schmitt Trigger enable 0 - Schmitt trigger input disabled 1 - Schmitt trigger input enabled Reset Source: mod_por_rst_n |
| 13:11 | PADCONFIG33_DEBOUNCE_SEL_PROXY | R/W | 0h | Selects the debouce period for the pad. Field values (others are reserved): 3'b000 - No debounce enabled 3'b001 - Use DBOUNCE_CFG1 register value 3'b010 - Use DBOUNCE_CFG2 register value 3'b011 - Use DBOUNCE_CFG3 register value 3'b100 - Use DBOUNCE_CFG4 register value 3'b101 - Use DBOUNCE_CFG5 register value 3'b110 - Use DBOUNCE_CFG6 register value 3'b'111 - Reserved Reset Source: mod_por_rst_n |
