The MCU is placed under the following conditions:
• All peripherals are disabled except when explicitly mentioned
• When the peripherals are enabled fPCLK2 = fHCLK and fPCLK1 = fHCLK/2
• When fHCLK > 8 MHz, the PLL is ON and the PLL input is equal to HSI/2 (4 MHz) or HSE (8 MHz) in bypass mode.
• Prefetch in ON (reminder: this bit must be set before clock setting and bus prescaling)
• All I/O pins are in input mode with a static value at VDD or VSS (no load)
• The Flash memory access time is adjusted to the fHCLK frequency (0 wait state from 0 to 24 MHz,1 wait state from 24 to 48 MHz and 2 wait states from 48 to 72 MHz)
