| This function sets reference clock of eFUSE controller. More... | |
| void | XNvm_EfuseEnableProgramming (void) |
| This function enables programming mode of eFUSE controller. More... | |
| int | XNvm_EfuseDisableProgramming (void) |
| This function disables programming mode of eFUSE controller. More... | |
| int | XNvm_EfuseResetReadMode (void) |
| This function disables Margin Read mode of eFUSE controller. More... | |
| void | XNvm_EfuseInitTimers (void) |
| This function initializes eFUSE controller timers. More... | |
| int | XNvm_EfuseSetupController (XNvm_EfuseOpMode Op, XNvm_EfuseRdMode RdMode) |

| u32 | XNvm_GetSysmonSupplyRegId (UINTPTR SysmonpsvSatBaseAddr) |
| This function reads root register ID where measurement is stored in Root SysMon. More... | |
| int | XNvm_EfuseTempAndVoltChecks (const XSysMonPsv *SysMonInstPtr) |
| This function performs the Temparature and Voltage checks to ensure that they are in limits before eFuse programming. More... | |
