• 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 pro-
grammer’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.
• Bit 6 – BODS: BOD Sleep
The BODS bit must be written to logic one in order to turn off BOD during sleep, see
on page
BODSE in MCUCR. To disable BOD in relevant sleep modes, both BODS and BODSE must
first be set to one. Then, to set the BODS bit, BODS must be set to one and BODSE must be
set to zero within four clock cycles.
The BODS bit is active three clock cycles after it is set. A sleep instruction must be executed
while BODS is active in order to turn off the BOD for the actual sleep mode. The BODS bit is
automatically cleared after three clock cycles.
• Bit 5 – BODSE: BOD Sleep Enable
BODSE enables setting of BODS control bit, as explained in BODS bit description. BOD dis-
able is controlled by a timed sequence.
• Bits 7:6 – Res: Reserved bits
These bits are reserved bits in the ATtiny87/167 and will always read as zero.
• Bit 5 – PRLIN: Power Reduction LIN / UART controller
Writing a logic one to this bit shuts down the LIN by stopping the clock to the module. When
waking up the LIN again, the LIN should be re initialized to ensure proper operation.
