CONFIG_I2S_STM32_PLLI2S_PLLR¶
Division factor for I2S clock
Type: int
Help¶
Division factor for the I2S clock. PLLR factor should be selected to ensure that the I2S clock frequency is less than or equal to 192MHz. Allowed values: 2-7
Direct dependencies¶
(I2S && BOARD_96B_ARGONKEY) || (I2S_STM32_USE_PLLI2S_ENABLE && I2S_STM32 && I2S)
