7647G–AVR–09/11
Power Reduction Register - PRR
• Bit 7 - Res: Reserved Bit
This bit is unused bit in the ATmega16/32/64/M1/C1, and will always read as zero.
• Bit 6 - PRCAN: Power Reduction CAN
Writing a logic one to this bit reduces the consumption of the CAN by stopping the clock to this
module. When waking up the CAN again, the CAN should be re initialized to ensure proper
operation.
• Bit 5 - PRPSC: Power Reduction PSC
Writing a logic one to this bit reduces the consumption of the PSC by stopping the clock to this
module. When waking up the PSC again, the PSC should be re initialized to ensure proper
operation.
• Bit 4 - PRTIM1: Power Reduction Timer/Counter1
Writing a logic one to this bit reduces the consumption of the Timer/Counter1 module. When
the Timer/Counter1 is enabled, operation will continue like before the setting of this bit.
• Bit 3 - PRTIM0: Power Reduction Timer/Counter0
Writing a logic one to this bit reduces the consumption of the Timer/Counter0 module. When
the Timer/Counter0 is enabled, operation will continue like before the setting of this bit.
• Bit 2 - PRSPI: Power Reduction Serial Peripheral Interface
Writing a logic one to this bit reduces the consumption of the Serial Peripheral Interface by
stopping the clock to this module. When waking up the SPI again, the SPI should be re initial-
ized to ensure proper operation.
• Bit 1 - PRLIN: Power Reduction LIN
Writing a logic one to this bit reduces the consumption of the UART controller by stopping the
clock to this module. When waking up the UART controller again, the UART controller should
be re initialized to ensure proper operation.
• Bit 0 - PRADC: Power Reduction ADC
Writing a logic one to this bit reduces the consumption of the ADC by stopping the clock to this
module. The ADC must be disabled before using this function. The analog comparator cannot
use the ADC input MUX when the clock of ADC is stopped.
