128kHz Internal Oscillator
ATmega16M1/32M1/64M1
Therefore it is recommended not to take the OSCCAL adjustments to a higher frequency than 1
MHz in order to keep the PLL in the correct operating range. The internal PLL is enabled only
when the PLLE bit in the register PLLCSR is set. The bit PLOCK from the register PLLCSR is
set when PLL is locked.
Both internal 1MHz RC Oscillator and PLL are switched off in Power-down and Standby sleep
modes.
Table 8-7.
Note:
Figure 8-3.
The 128kHz internal Oscillator is a low power Oscillator providing a clock of 128kHz. The fre-
quency is nominal at 3V and 25°C. This clock is used by the Watchdog Oscillator.
