8371A–AVR–08/12
Writing a logic one to this bit shuts down the Timer/Counter0 module. When the Timer/Counter0 is enabled, operation will
continue like before the shutdown.
z Bit 3 – PRTIM1: Power Reduction Timer/Counter1
Writing a logic one to this bit shuts down the Timer/Counter1 module. When the Timer/Counter1 is enabled, operation will
continue like before the shutdown.
z Bit 2 – PRSPI: Power Reduction SPI
Writing a logic one to this bit shuts down the SPI by stopping the clock to the module. When waking up the SPI again, the
SPI should be re-initialized to ensure proper operation.
z Bit 1 – PRUSART0: Power Reduction USART0
Writing a logic one to this bit shuts down the USART0 module. When the USART0 is enabled, operation will continue like
before the shutdown.
z Bit 0 – PRADC: Power Reduction ADC
Writing a logic one to this bit shuts down the ADC. The ADC must be disabled before shut down. The analog comparator
cannot be used when the ADC is shut down.
