• Manufacturer Part Number: ATmega88PA Automotive
• Manufacturer: Atmel Corporation

• Bit 2 – PRSPI: Power Reduction Serial Peripheral Interface
If using debugWIRE On-chip Debug System, this bit should not be written to one.
Writing a logic one to this bit shuts down the Serial Peripheral Interface by stopping the clock
to the module. When waking up the SPI again, the SPI should be re initialized to ensure
proper operation.
• Bit 1 – PRUSART0: Power Reduction USART0
Writing a logic one to this bit shuts down the USART by stopping the clock to the module.
When waking up the USART again, the USART should be re initialized to ensure proper
operation.
• 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 use the ADC input MUX when the ADC is shut down.
