ATmega640/1280/1281/2560/2561
• Bit 2 - PRUSART3: Power Reduction USART3
Writing a logic one to this bit shuts down the USART3 by stopping the clock to the module.
When waking up the USART3 again, the USART3 should be re initialized to ensure proper
operation.
• Bit 1 - PRUSART2: Power Reduction USART2
Writing a logic one to this bit shuts down the USART2 by stopping the clock to the module.
When waking up the USART2 again, the USART2 should be re initialized to ensure proper
operation.
• Bit 0 - PRUSART1: Power Reduction USART1
Writing a logic one to this bit shuts down the USART1 by stopping the clock to the module.
When waking up the USART1 again, the USART1 should be re initialized to ensure proper
operation.
