Function Documentation

§ DL_COMP_enablePower()

__STATIC_INLINE void DL_COMP_enablePower ( COMP_Regs * comp )

Enables the Peripheral Write Enable (PWREN) register for the COMP.

Before any peripheral registers can be configured by software, the peripheral itself must be enabled by writing the ENABLE bit together with the appropriate KEY value to the peripheral's PWREN register.

Note: For power savings, please refer to DL_COMP_enable

Parameters

[in] comp Pointer to the register overlay for the peripheral

§ DL_COMP_disablePower()

__STATIC_INLINE void DL_COMP_disablePower ( COMP_Regs * comp )

Disables the Peripheral Write Enable (PWREN) register for the COMP.

When the PWREN.ENABLE bit is cleared, the peripheral's registers are not accessible for read/write operations.

Note: This API does not provide large power savings. For power savings, please refer to DL_COMP_enable

Parameters

[in] comp Pointer to the register overlay for the peripheral

§ DL_COMP_isPowerEnabled()

__STATIC_INLINE bool DL_COMP_isPowerEnabled ( COMP_Regs * comp )

Returns if the Peripheral Write Enable (PWREN) register for the COMP is enabled.

Before any peripheral registers can be configured by software, the peripheral itself must be enabled by writing the ENABLE bit together with the appropriate KEY value to the peripheral's PWREN register.

When the PWREN.ENABLE bit is cleared, the peripheral's registers are not accessible for read/write operations.

Parameters

[in] comp Pointer to the register overlay for the peripheral

Returns: The status of the peripheral power; true if peripheral register access is enabled; false if peripheral register access is disabled

§ DL_COMP_reset()

__STATIC_INLINE void DL_COMP_reset ( COMP_Regs * comp )

Resets comparator peripheral.

Parameters

[in] comp Pointer to the register overlay for the peripheral

§ DL_COMP_isReset()

__STATIC_INLINE bool DL_COMP_isReset ( COMP_Regs * comp )

Returns if comparator was reset.

Parameters

[in] comp Pointer to the register overlay for the peripheral

Returns: true If peripheral was reset; false If peripheral wasn't reset

§ DL_COMP_init()

__STATIC_INLINE void DL_COMP_init	(	COMP_Regs *	comp,

Initializes all the common configurable options for the COMP peripheral. Any other custom configuration can be done after calling this API. The COMP is not enabled in this API.

Parameters

[in]	comp	Pointer to the register overlay for the peripheral
[in]	config	Configuration for COMP peripheral

[in] comp Pointer to the register overlay for the peripheral

Returns: Returns the enabled status of the comparator

Return values

true	The comparator peripheral is enabled
false	The comparator peripheral is disabled

Parameters

[in] comp Pointer to the register overlay for the peripheral

§ DL_COMP_setCompMode()

__STATIC_INLINE void DL_COMP_setCompMode	(	COMP_Regs *	comp,
		DL_COMP_MODE	mode
	)

Set the comparator operating mode.

The clock control for comparator is managed by SYSCTL, SYSCTL knows if comparator module is enabled and at also knows if it is in ultra-low power mode or fast mode. User needs to ensure the proper bus clock is selected for different comparator operation mode.
