| * Macros for tcpc_config_t flags field. |

| * Bit 0 --> Polarity for TCPC alert. Set to 1 if alert is active high. |
| * Bit 1 --> Set to 1 if TCPC alert line is open-drain instead of push-pull. |
| * Bit 2 --> Polarity for TCPC reset. Set to 1 if reset line is active high. |
| * Bit 3 --> Set to 1 if TCPC is using TCPCI Revision 2.0 |
| * Bit 4 --> Set to 1 if TCPC is using TCPCI Revision 2.0 but does not support |
| * the vSafe0V bit in the EXTENDED_STATUS_REGISTER |
| * Bit 5 --> Set to 1 to prevent TCPC setting debug accessory control |
| * Bit 6 --> TCPC controls VCONN (even when CONFIG_USB_PD_TCPC_VCONN is off) |
| * Bit 7 --> TCPC controls FRS (even when CONFIG_USB_PD_FRS_TCPC is off) |
| * Bit 8 --> TCPC enable VBUS monitoring |
| * Bit 10 --> TCPC enable voltage alarm |
