Register Description
ATtiny2313A/4313
MCUCR – MCU Control Register
PRR – Power Reduction Register
For analog input pins, the digital input buffer should be disabled at all times. An analog signal
level close to V
input buffers can be disabled by writing to the Digital Input Disable Register (DIDR). See
– Digital Input Disable Register” on page 168
The Sleep Mode Control Register contains control bits for power management.
• Bits 6, 4 – SM1..0: Sleep Mode Select Bits 1 and 0
These bits select between the four available sleep modes as shown in
Table 7-2.
Note:
• 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.
The Power Reduction Register provides a method to reduce power consumption by allowing
peripheral clock signals to be disabled.
• Bits 7..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.
