5.2.5 Initialization and Configuration functions
5.2.5.1 COMP_DeInit
Function Name
void COMP_DeInit ( uint32_t COMP_Selection)
Function Description
Deinitializes COMP peripheral registers to their default reset
values.
Parameters
 COMP_Selection.
Return values
 None.
Notes
 Deinitialization can't be performed if the COMP configuration
is locked. To unlock the configuration, perform a system
reset.
5.2.5.2 COMP_Init
Function Name
void COMP_Init ( uint32_t COMP_Selection,
COMP_InitTypeDef * COMP_InitStruct)
Function Description
Initializes the COMP peripheral according to the specified
parameters in COMP_InitStruct.
Parameters
 COMP_Selection : the selected comparator. This parameter
can be COMP_Selection_COMPx where x can be 1 to 7 to
select the COMP peripheral.
 COMP_InitStruct : pointer to an COMP_InitTypeDef
structure that contains the configuration information for the
specified COMP peripheral. COMP_InvertingInput specifies
the inverting input of COMPCOMP_NonInvertingInput
specifies the non inverting input of COMPCOMP_Output
