PRR – Power Reduction Register
Bits 7:5 – Res: Reserved Bits
These bits are reserved and will always read as zero.
Bit 4 – PRTWI: Power Reduction Two-Wire Interface
Writing a logic one to this bit shuts down the Two-Wire Interface module.
Bit 3 – PRSPI: Power Reduction Serial Peripheral Interface
Writing a logic one to this bit shuts down the Serial Peripheral Interface module.
Bit 2 – 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.
Bit 1 – PRTIM0: Power Reduction Timer/Counter0
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.
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.
