Enable or disable the BEEP function.

Note:

Initialisation of BEEP and LS RC calibration must be done before.

Parameters:

NewState

Indicates the new state of the BEEP function.

Return values:

None

References BEEP, BEEP_CSR2_BEEPEN, DISABLE, and IS_FUNCTIONAL_STATE.

Deinitializes the BEEP peripheral registers to their default reset values.

Parameters:

None

Return values:

None

References BEEP, BEEP_CSR1_RESET_VALUE, and BEEP_CSR2_RESET_VALUE.

Initializes the BEEP function according to the specified parameters.

Note:

The LS RC calibration must be performed before calling this function.

Parameters:

BEEP_Frequency

Frequency selection. This parameter can be one of the values of BEEP_Frequency_TypeDef.

Return values:

None

Enable or disable the LS clock source connection to TIM for measurement.

Parameters:

NewState

Indicates the new state of the LS clock to TIM connection

Return values:

None

References BEEP, BEEP_CSR1_MSR, DISABLE, and IS_FUNCTIONAL_STATE.

Update CSR register with the measured LSI frequency.

Note:

BEEP must be disabled to avoid unwanted interrupts.

Prescaler calculation: A is the integer part of LSIFreqkHz/4 and x the decimal part. x <= A/(1+2A) is equivalent to A >= x(1+2A) and also to 4A >= 4x(1+2A) [F1] but we know that A + x = LSIFreqkHz/4 ==> 4x = LSIFreqkHz-4A so [F1] can be written : 4A >= (LSIFreqkHz-4A)(1+2A)

Parameters:

LSIFreqHz

Low Speed RC frequency measured by timer (in Hz).

Return values:

None
