PLL4DIVM=B_0x0, PLL4BYP=B_0x0, PLL4SEL=B_0x0
RCC PLL4 configuration register 1
PLL4DIVN | PLL4 Integer part for the VCO multiplication factor |
PLL4DIVM | PLL4 reference input clock divide frequency ratio 0 (B_0x0): Not applicable when PLL is enabled 1 (B_0x1): reference clock is divided by 1 (min value) 2 (B_0x2): reference clock is divided by 2 63 (B_0x3F): reference clock is divided by 63 |
PLL4BYP | PLL4 bypass 0 (B_0x0): PLL output is driven by the VCO, via the optional POSTDIV division 1 (B_0x1): PLL output is bypassed and driven by the PLL reference clock (default after reset) |
PLL4SEL | PLL4 source selection of the reference clock 0 (B_0x0): hsi_ck selected as reference clock 1 (B_0x1): msi_ck selected as reference clock 2 (B_0x2): hse_ck selected as reference clock 3 (B_0x3): I2S_CKIN selected as reference clock |
