Test del chip di Genova - post tuning 1 IREF trim
Per ottenere una corrente di 4 µA si modifica la posizione dei jumper, posizionandoli in corrispondenza dei bit 1 e 2. Si ottiene una corrente di 3.95 µA.
2 VREF-ADC trim
Si modifica il valore di AdcRefTrim in modo che la tensione misurata dal multimetro sia quanto più vicina possibile a 0.9 V.
Si fissa AdcRefTrim=15, ottenendo 0.8868 V.
3 VDD trim
Nel file di configurazione si modificano i valori di SldoAnalogTrim e SldoDigitalTrim affinché le tensioni VDDD e VDDA misurate dal multimetro siano quanto più vicine possibile a 1.2 V.
Il valore scelto per SldoDigitalTrim è 22, che restituisce 1.2029 V.
Il valore scelto per SldoDigitalTrim è 21, che restituisce 1.2037 V.
