electrical characteristics over recommended ranges of supply voltage and operating free-air
temperature (unless otherwise noted) (continued)
main DCO characteristics
D Individual devices have a minimum and maximum operation frequency. The specified parameters for
f(DCOx0) to f(DCOx7) are valid for all devices.
D All ranges selected by Rsel(n) overlap with Rsel(n+1): Rsel0 overlaps Rsel1, ... Rsel6 overlaps Rsel7.
D DCO control bits DCO0, DCO1, and DCO2 have a step size as defined by parameter S
DCO.
D Modulation control bits MOD0 to MOD4 select how often f(
DCO+1) is used within the period of 32 DCOCLK
cycles. The frequency f(DCO) is used for the remaining cycles. The frequency is an average equal to:
