+ * HCLK(Hz) = 120000000
+ * AHB Prescaler = 1

+ * APB2 Prescaler = 1
+ * MSI Frequency(Hz) = 48000000
+ * PLL_M = 12
+ * PLL_N = 60
+ * PLL_P = 2
+ * PLL_Q = 2
+ * VDD(V) = 3.3
+ * Main regulator output voltage = Scale1 mode
+ * Flash Latency(WS) = 5
+ * The USB clock configuration from PLLSAI:
+ * PLLSAIP = 8 FIXME
+ * PLLSAIN = 384 FIXME
+ * PLLSAIQ = 7 FIXME
+ * @param None
