PRR – Power Reduction Register
• Bits 4:3 – SM[1:0]: Sleep Mode Select Bits 1:0
These bits select between the three available sleep modes as shown in
Table 7-2.
The Power Reduction Register provides a method to reduce power consumption by allowing
peripheral clock signals to be disabled.
• Bits 7:2 – Res: Reserved Bits
These bits are reserved and will always read as zero.
• 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 be used when the ADC is shut down.
