VDDA

(1)

1. When the ADC is used, refer to Table 51: ADC characteristics.

Analog operating voltage

(ADC not used)

Must be the same potential

as VDD

(2)

2. It is recommended to power VDD and VDDA from the same source. A maximum difference of 300 mV

between VDD and VDDA can be tolerated during power-up and operation.
