electrical characteristics over recommended ranges of supply voltage and operating free-air
temperature (unless otherwise noted) (continued)
main DCO characteristics
D
All ranges selected by RSELx overlap with RSELx + 1: RSELx = 0 overlaps RSELx = 1, ... RSELx = 14
overlaps RSELx = 15.
D
DCO control bits DCOx have a step size as defined by parameter S
DCO
.
D
Modulation control bits MODx select how often f
DCO(RSEL,DCO+1)
is used within the period of 32 DCOCLK
cycles. The frequency f
DCO(RSEL,DCO)
is used for the remaining cycles. The frequency is an average equal
to:
