CONFIG_I2S_STM32_PLLI2S_PLLN¶
Multiplier factor for PLLI2S VCO output clock
Type: int
Help¶
Multiply factor for the audio PLL (PLLI2S) VCO output clock. PLLN factor should be selected to ensure that the VCO output frequency ranges from 100 to 432 MHz. Allowed values: 50-432
Direct dependencies¶
(I2S && BOARD_96B_ARGONKEY) || (I2S_STM32_USE_PLLI2S_ENABLE && I2S_STM32 && I2S)
(Includes any dependencies from if’s and menus.)
Defaults¶
- 192 if
