Detailed Description

Function Documentation

DDL_COMP_Disable()

__STATIC_INLINE void DDL_COMP_Disable

(

COMP_TypeDef *

COMPx

)

Disable comparator instance.

Parameters

COMPx

COMP instance.

Return values

None

Definition at line 518 of file g32r4xx_ddl_comp.h.

DDL_COMP_Enable()

__STATIC_INLINE void DDL_COMP_Enable

(

COMP_TypeDef *

COMPx

)

Enable comparator instance.

Parameters

COMPx

COMP instance.

Return values

None

Note

After enable from off state, comparator startup time is needed.

Definition at line 508 of file g32r4xx_ddl_comp.h.

DDL_COMP_IsEnabled()

__STATIC_INLINE uint32_t DDL_COMP_IsEnabled

(

COMP_TypeDef *

COMPx

)

Get comparator enable state.

Parameters

COMPx

COMP instance.

Return values

State

of bit (1 or 0). 0: comparator instance is disabled. 1: comparator instance is enabled.

Definition at line 530 of file g32r4xx_ddl_comp.h.

DDL_COMP_IsLocked()

__STATIC_INLINE uint32_t DDL_COMP_IsLocked

(

COMP_TypeDef *

COMPx

)

Get comparator lock state.

Parameters

COMPx

COMP instance.

Return values

State

of bit (1 or 0). 0: comparator instance is unlocked.

• 1: comparator instance is locked.

Definition at line 554 of file g32r4xx_ddl_comp.h.

DDL_COMP_Lock()

__STATIC_INLINE void DDL_COMP_Lock

(

COMP_TypeDef *

COMPx

)

Lock comparator instance.

Parameters

COMPx

COMP instance.

Return values

None

Note

Once locked, comparator configuration can no longer be modified until next reset.

The only way to unlock the comparator is a device hardware reset.

Definition at line 542 of file g32r4xx_ddl_comp.h.

DDL_COMP_ReadOutputLevel()

__STATIC_INLINE uint32_t DDL_COMP_ReadOutputLevel

(

COMP_TypeDef *

COMPx

)

Read comparator output level.

Parameters

COMPx

COMP instance.

Return values

Returned

value can be one of the following values: DDL_COMP_OUTPUT_LEVEL_LOW DDL_COMP_OUTPUT_LEVEL_HIGH

Note

The comparator output level depends on the selected polarity. If the polarity is not inverted:

• Comparator output is low level when the input plus is lower than the input minus.
• Comparator output is high level when the input plus is higher than the input minus. If the polarity is inverted:
• Comparator output is high level when the input plus is lower than the input minus.
• Comparator output is low level when the input plus is higher than the input minus.
