Figure 11. Distribution of ADC codes when ART is OFF and VIN = 1.65 V
In the same conditions, when ART is OFF, using the Default STM32 configuration with
STM32F2xx or STM32F405/F415/F407/F417 gives a maximum dispersion of 24 LSB (refer
to Table 3) while, in this case, the maximum dispersion is 10 LSB.
This confirms that the default STM32 configuration embedded on these products allows to
achieve more than 50 % of dispersion code versus STM32F2xx/F405/F415/F407/F417, and
about 75 % when one of the options is active.
3.
ADC measurements when (Data+Instruction) cache ON + Prefetch OFF
The following table and graph show the ADC code distribution when (Data + Instruction)
cache ON and prefetch OFF at three different conditions: default STM32 configuration,
Option 1 and Option 2 are active.
