Table 50: RH850/F1K Power supply architecture with mixed supply 5V & 3.3V
Case 7 – Mixed Supply 5V & 3.3V
EVCC = 3.3V
A0VREF = 5V
AP0 – Port usable with analog or digital function
P8 – Port usable with analog or digital function, analog input
voltage limited to max. 3.3V, reduced AD conversion range between 0V
to 3.3V
P9 – Port usable with analog or digital function, analog input
voltage limited to max. 3.3V, reduced AD conversion range between 0V
to 3.3V
AP1 – Port usable with analog or digital function
P18 – Port usable with analog or digital function, analog input
voltage limited to max. 3.3V, reduced AD conversion range between 0V
to 3.3V
Analog port function limitation applies to P8, P9 and P18
