Table 52: RH850/F1K Power supply architecture with mixed supply 5V & 3.3V
Case 9 – Mixed Supply 5V & 3.3V
Condition
REGVCC = 3.3V
EVCC = 3.3V
A0VREF = 3.3V
A1VREF = 5V
Port Function
AP0 – Port usable with analog or digital function
P8 – Port usable with analog or digital function
P9 – Port usable with analog or digital function
