Table 47: RH850/F1K Power supply architecture with mixed supply 5V & 3.3V
Case 3 – Mixed Supply 5V & 3.3V
Condition
REGVCC = 5V
EVCC = 5V
A0VREF = 3.3V
A1VREF = 5V
Port Function
AP0 – Port usable with analog or digital function
P8 – Port usable with analog or digital function, analog input
voltage limited to max. 3.3V. When analog input terminal is over 3.3V,
do not include the input into an AD scan group.
P9 – Port usable with analog or digital function, analog input
voltage limited to max. 3.3V. When analog input terminal is over 3.3V,
do not include the input into an AD scan group.
AP1 – Port usable with analog or digital function
P18 – Port usable with analog or digital function
Limitation
Analog port function limitation applies to P8 and P9

Operation permitted
