UM1940
HAL RCC Generic Driver
DocID028236 Rev 2
451/1371
Parameters:
__PLLI2SN__: specifies the multiplication factor for
PLLI2S VCO output clock This parameter must be
a number between Min_Data = 192 and Max_Data
= 432.
__PLLI2SR__: specifies the division factor for I2S
clock This parameter must be a number between
Min_Data = 2 and Max_Data = 7.
Notes:
This macro must be used only when the PLLI2S is
disabled. PLLI2S clock source is common with the
main PLL (configured in HAL_RCC_ClockConfig()
API).
You have to set the PLLI2SN parameter correctly
to ensure that the VCO output frequency is
between Min_Data = 192 and Max_Data = 432
MHz.
You have to set the PLLI2SR parameter correctly
to not exceed 192 MHz on the I2S clock frequency.
__HAL_RCC_I2S_CONFIG
Description:
Macro to configure the I2S clock source (I2SCLK).
Parameters:
__SOURCE__: specifies the I2S clock source. This
parameter can be one of the following values:
RCC_I2SCLKSOURCE_PLLI2S: PLLI2S
clock used as I2S clock source.
RCC_I2SCLKSOURCE_EXT: External clock
mapped on the I2S_CKIN pin used as I2S
clock source.
Notes:
This function must be called before enabling the
I2S APB clock.
