Figure 35-4. DFLL Open Loop Frequency Variation
(1)(2)
Notes: 1. The plot shows a typical open loop mode behavior with COARSE= 99 and FINE= 255.
2. These values are based on simulation and characterization of other AVR microcontrollers manufactured in the same pro-
cess technology. These values are not covered by test limits in production.
