16.2.4 Initialization and Configuration
16.2.4.1 OPAMP_DeInit
Function Name
void OPAMP_DeInit ( uint32_t OPAMP_Selection)
Function Description
Deinitializes OPAMP peripheral registers to their default reset
values.
Parameters
 OPAMP_Selection.
Return values
 None.
Notes
 Deinitialization can't be performed if the OPAMP configuration
is locked. To unlock the configuration, perform a system
reset.
16.2.4.2 OPAMP_Init
Function Name
void OPAMP_Init ( uint32_t OPAMP_Selection,
OPAMP_InitTypeDef * OPAMP_InitStruct)
Function Description
Initializes the OPAMP peripheral according to the specified
parameters in OPAMP_InitStruct.
Parameters
 OPAMP_Selection : the selected OPAMP. This parameter
can be OPAMP_Selection_OPAMPx where x can be 1 to 4 to
select the OPAMP peripheral.
 OPAMP_InitStruct : pointer to an OPAMP_InitTypeDef
structure that contains the configuration information for the
specified OPAMP peripheral. OPAMP_InvertingInput
specifies the inverting input of
OPAMPOPAMP_NonInvertingInput specifies the non
inverting input of OPAMP
 OPAMP_InvertingInput :
 OPAMP_NonInvertingInput :
Return values
 None.
Notes
 If the selected OPAMP is locked, initialization can't be
performed. To unlock the configuration, perform a system
reset.
