PRR - Power Reduction Register

• Bit 7 - PRPSC2: Power Reduction PSC2

Writing a logic one to this bit reduces the consumption of the PSC2 by stopping the clock to this

module. When waking up the PSC2 again, the PSC2 should be re initialized to ensure proper

operation.

• Bit 6 - Reserved

• Bit 5 - PRPSCR: Power Reduction PSC reduced

Writing a logic one to this bit reduces the consumption of the PSCR by stopping the clock to this

module. When waking up the PSCR again, the PSCR 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 - Reserved

• Bit 2 - PRSPI: Power Reduction Serial Peripheral Interface

Writing a logic one to this bit reduces the consumption of the Serial Peripheral Interface by stop-

ping the clock to this module. When waking up the SPI again, the SPI should be re initialized to

ensure proper operation.

• Bit 1 - Reserved

• 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.
