All I/O pins are in analog input configuration
The Flash access time is adjusted to f
1 wait state above)
Prefetch is ON when the peripherals are enabled, otherwise it is OFF
When the peripherals are enabled, f
PLL is used for frequencies greater than 8 MHz
AHB prescaler of 2, 4, 8 and 16 is used for the frequencies 4 MHz, 2 MHz, 1 MHz and
500 kHz respectively
A development tool is connected to the board and the parasitic pull-up current is around
30 µA
