For all configurations, the default HSI clock will be used for the microcontroller. You

are allowed to use the gpio functions available from the stm$32$f$446$zeLib library.

STEP$1$: Normal operation

The project contains a code that only executes an infinite loop containing the

increment of a variable in the following conditions:

$$ All bus prescalers are set to the minimum value $($i$.$e$.$ maximum frequency$)$

$$ clock for ports A to H are enabled.

$$ Measure the supply current IDD in this configuration.
