The 5509a datasheet lists 3 non-overlapping core voltage ranges associated with 3 clock frequencies.
for 108MHz: CVDD Device supply voltage min=1.14 typ=1.20 max=1.26 Volts
for 144MHz: CVDD Device supply voltage min=1.28 typ=1.35 max=1.42 Volts
for 200MHz: CVDD Device supply voltage min=1.55 typ=1.60 max=1.65 Volts
Does this mean if I am running at CVDD core = 1.35V I cannot run the processor down to 100MHz to save power when needed?
