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:

NOTE 1: The signal applied to the USART0/USART1 receive signal/terminal (URXD0/1) should meet the timing requirements of t(τ) to ensure

that the URXS flip-flop is set. The URXS flip-flop is set with negative pulses meeting the minimum-timing condition of t(τ). The operating

conditions to set the flag must be met independently from this timing constraint. The deglitch circuitry is active only on negative

transitions on the URXD0/1 line.
