• 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 stopping 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.
