PRR – Power Reduction Register
• Bit 5 – BODSE: BOD Sleep Enable
BODSE enables setting of BODS control bit, as explained in BODS bit description. BOD disable
is controlled by a timed sequence.
• Bits 7:5 – Reserved
These bits are reserved and will always read as zero.
• Bit 4 – PRLCD: Power Reduction LCD
Writing logic one to this bit shuts down the LCD controller. The LCD controller must be disabled
and the display discharged before shut down. See "Disabling the LCD" on page 217 for details
on how to disable the LCD controller.
• Bit 3 – PRTIM1: Power Reduction Timer/Counter1
Writing logic one to this bit shuts down the Timer/Counter1 module. When Timer/Counter1 is
enabled, operation will continue like before the shutdown.
• Bit 2 – PRSPI: Power Reduction Serial Peripheral Interface
Writing 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 – PRUSART: Power Reduction USART
Writing 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 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.
