ATmega8U2/16U2/32U2

• Bit 1 – PLLE: PLL Enable

When the PLLE is set, the PLL is started. Note that the Calibrated 8 MHz Internal RC oscillator is

automatically enabled when the PLLE bit is set and with PINMUX (see PLLFRQ register) is set.

The PLL must be disabled before entering Power down mode in order to stop Internal RC Oscil-

lator and avoid extra-consumption.

• Bit 0 – PLOCK: PLL Lock Detector

When the PLOCK bit is set, the PLL is locked to the reference clock. After the PLL is enabled, it

takes about several ms for the PLL to lock. To clear PLOCK, clear PLLE.
