1. Enabling of the Timer/Counter1 Compare match outputs and Timer/Counter1 PWM Outputs OC1A/OC1B and OC1A/OC1B
2. Note that the PCINT0 Interrupt is only enabled if both the Global Interrupt Flag is enabled, the PCIE0 flag in GIMSK is set
3. The Two-wire and Three-wire USI-modes are described in “Universal Serial Interface – USI” on page 80.
4. Shift clock (SCL) hold for USI is in described “Universal Serial Interface – USI” on page 80.
5. USI start up interrupt is enabled if both the Global Interrupt Flag is enabled and the USISIE flag in the USICR Register is set
6. Data Output (DO) is valid in USI Three-wire mode and the operation is described in “Universal Serial Interface – USI” on
7. Operation of the data pin SDA in USI Two-wire mode and DI in USI Three-wire mode in “Universal Serial Interface – USI” on
8. Not operator is marked with “~”.
