32.7.3 Phase Locked Loop (PLL) Characteristics
32.7.4 120MHz RC Oscillator (RC120M) Characteristics
Note: 1. 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.
32.7.5 System RC Oscillator (RCSYS) Characteristics
32.8 Flash Characteristics
Table 32-17 gives the device maximum operating frequency depending on the number of flash
wait states and the flash read mode. The FSW bit in the FLASHCDW FSR register controls the
number of wait states used when accessing the flash memory.
