Bit 3 – PRPTC: Power Reduction PTC

Power Reduction PTC

Writing a logic one to this bit shuts down the PTC module. When the PTC is enabled, operation will continue like before the shutdown.

Bit 2 – PRUSART2: Power Reduction USART2

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 1 – PRSPI1: Power Reduction Serial Peripheral Interface

Power Reduction Serial Peripheral Interface

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 0 – PRTWI1: Power Reduction TWI1

Power Reduction TWI1

Writing a logic one to this bit shuts down the TWI1 by stopping the clock to the module. When waking up the TWI1 again, the TWI1 should be re initialized to ensure proper operation.
