Register Description
SMCR – Sleep Mode Control Register
The Sleep Mode Control Register contains control bits for power management.
• Bits [7:4]: Reserved
These bits are unused in the ATmega48A/48PA/88A/88PA/168A/168PA/328/328P, and will
always be read as zero.
• Bits 3:1 – SM[2:0]: Sleep Mode Select Bits 2, 1, and 0
These bits select between the five available sleep modes as shown in
Table 9-2.
Note:
• Bit 0 – 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.
