Register Description
MCUCR – MCU Control Register
PRR – Power Reduction Register
Refer to
able Register 1” on page 162
The MCU Control Register contains control bits for power management.
• Bit 5 – SE: Sleep Enable
The SE bit must be written to logic one to make the MCU enter the sleep mode when the SLEEP
instruction is executed. To avoid the MCU entering the sleep mode unless it is the programmer’s
purpose, it is recommended to write the Sleep Enable (SE) bit to one just before the execution of
the SLEEP instruction and to clear it immediately after waking up.
• Bits 4, 3 – SM1:0: Sleep Mode Select Bits 2:0
These bits select between the three available sleep modes as shown in
Table 7-2.
• Bit 2 – Res: Reserved Bit
This bit is reserved and will always read zero.
The Power Reduction Register provides a method to reduce power consumption by allowing
peripheral clock signals to be disabled.
• Bits 7, 6, 5, 4 – Res: Reserved Bits
These bits are reserved and will always read zero.
• Bit 3 – 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.
