7.6.4.12. function Mcu_ASysCtl_ConfigADCGlobalSOC

void Mcu_ASysCtl_ConfigADCGlobalSOC(
    uint32 BaseAddr,
    uint8 AdcSelect
)

Brief: Configures the ADC Global SOC Force Select register (ADCSOCFRCGBSEL).

Writes ADCSOCFRCGBSEL at the given base address with the ADC instance select mask, selecting which ADC instances participate in the global software trigger.

Parameters:

BaseAddr Base address of the ADC global register block
AdcSelect ADC instance selection mask (e.g. ASYSCTL_ADCSOCFRCGBSEL_ADCA, etc.)

Returns:

None

Return: None

Note: This API is a general-purpose ASysCtl service and is available unconditionally (not gated by a feature-specific compile switch). It is intended to be called by any module that requires ADC global SOC instance selection (e.g. Cdd_Adc when CDD_ADC_GLBSW_TRIG_API is STD_ON).

Precondition: Mcu_Init() must have been called.

Postcondition: ADCSOCFRCGBSEL register written with AdcSelect.

7.6.4.13. function Mcu_ASysCtl_ForceADCGlobalSOC

void Mcu_ASysCtl_ForceADCGlobalSOC(
    uint32 BaseAddr,
    uint32 SocMask
)

Brief: Forces the ADC Global SOC trigger register (ADCSOCFRCGB).

Writes ADCSOCFRCGB at the given base address with the SOC mask to simultaneously trigger the selected SOCs across all ADC instances configured via ADCSOCFRCGBSEL.

Parameters:

BaseAddr Base address of the ADC global register block
SocMask SOC trigger mask (one bit per SOC to trigger)

Returns:

None

Return: None

Note: This API is a general-purpose ASysCtl service and is available unconditionally (not gated by a feature-specific compile switch). It is intended to be called by any module that requires ADC global SOC force triggering (e.g. Cdd_Adc when CDD_ADC_GLBSW_TRIG_API is STD_ON).

Precondition: Mcu_Init() must have been called.

Postcondition: ADCSOCFRCGB register written with SocMask.

7.6.4.14. function Mcu_SysCtl_ConfigEPWMXLink

void Mcu_SysCtl_ConfigEPWMXLink(
    uint32 EPWMXLinkMask
)

Brief: Configures the EPWM XLINK feature by writing the EPWMXLINKCFG register.

Writes the EPWMXLINKCFG register at DEVCFG_BASE to enable the XLINK feature for the specified ePWM instances. Uses read-modify-write to set only the requested bits without affecting other instances.

The EPWMXLinkMask parameter is a bitwise OR of SYSCTL_EPWMXLINKCFG_EPWMn macros:

SYSCTL_EPWMXLINKCFG_EPWM1 (0x00001U) — Enable EPWM1 for XLINK
SYSCTL_EPWMXLINKCFG_EPWM2 (0x00002U) — Enable EPWM2 for XLINK
…
SYSCTL_EPWMXLINKCFG_EPWM18 (0x20000U) — Enable EPWM18 for XLINK

Parameters:

EPWMXLinkMask Bitmask of SYSCTL_EPWMXLINKCFG_EPWMn bits to enable

Returns:

None

Return: None

Note: This API is intended to be called by Cdd_Pwm when the XLINK feature is enabled for an ePWM instance. The register is at DEVCFG_BASE and is exclusively writable by CPU1.LINK2.

Precondition: Mcu_Init() must have been called.

Postcondition: EPWMXLINKCFG register OR-updated with EPWMXLinkMask.

7.6.4.15. function Mcu_ASysCtl_CommitLock

void Mcu_ASysCtl_CommitLock(
    Mcu_ASysCtlLockType LockMask
)

Brief: Commits (locks) the specified ASysCtl registers.

This function applies the one-time write-lock to ASysCtl registers (ASYSCTL_O_LOCK) for the registers specified by LockMask. Lock bits are irreversible until system reset.

Values of Mcu_ASysCtlLockType can be OR-combined to lock multiple registers:

MCU_ASYSCTL_LOCK_TSNSCTL — Temperature Sensor Control
MCU_ASYSCTL_LOCK_ANAREFCTL — Analog Reference Control
MCU_ASYSCTL_LOCK_VMONCTL — Voltage Monitor Control
MCU_ASYSCTL_LOCK_CMPHPMXSEL — CMPSS HP positive mux (CMP1-CMP10)
MCU_ASYSCTL_LOCK_CMPLPMXSEL — CMPSS LP positive mux (CMP1-CMP10)
MCU_ASYSCTL_LOCK_CMPHNMXSEL — CMPSS HN negative mux
MCU_ASYSCTL_LOCK_CMPLNMXSEL — CMPSS LN negative mux
MCU_ASYSCTL_LOCK_VREGCTL — Voltage Regulator Control
MCU_ASYSCTL_LOCK_CMPHPMXSEL1 — CMPSS HP positive mux (CMP11-CMP12)
MCU_ASYSCTL_LOCK_CMPLPMXSEL1 — CMPSS LP positive mux (CMP11-CMP12)

Parameters:

LockMask Bitmask of Mcu_ASysCtlLockType values to lock

Returns:

None

Return: None

Precondition: Mcu_Init() must be called before calling this function.

Postcondition: Specified ASysCtl registers are locked until next system reset.

7.6.4.16. function Mcu_GetRamState

Mcu_RamStateType Mcu_GetRamState(
    void 
)

Brief: This service provides the actual status of the microcontroller Ram.

This API is not checking actual RAM status. So no actions are performed and returns RAM VALID

Returns:

MCU_RAMSTATE_INVALID Invalid Ram status
MCU_RAMSTATE_VALID Valid Ram status

Return: Mcu_RamStateType - Ram State Type

Precondition: This API is available only if MCU_CFG_GET_RAM_STATE_API is STD_ON

Postcondition: None
