timer
If one of the timer registers which is synchronized to the asynchronous timer2 clock
is written in the cycle before a overflow interrupt occurs, the interrupt may be lost.
Problem Fix/Workaround
Always check that the Timer2 Timer/Counter register, TCNT2, does not have the
value 0xFF before writing the Timer2 Control Register, TCCR2, or Output Compare
Register, OCR2.

Register, OCR2.
Some display types with high serial resistance (>20 kΩ) inside the glass can result
in dim segments on the LCD
Problem Fix/Workaround
Add a 1 nF (0.47 - 1.5 nF) capacitor between each common pin and ground.
The JTAG instruction IDCODE is not working correctly. Data to succeeding devices
are replaced by all-ones during Update-DR.
Problem Fix / Workaround

If ATmega169 is the only device in the scan chain, the problem is not visible.
Select the Device ID Register of the ATmega169 by issuing the IDCODE
instruction or by entering the Test-Logic-Reset state of the TAP controller to
read out the contents of its Device ID Register and possibly data from
succeeding devices of the scan chain. Issue the BYPASS instruction to the
ATmega169 while reading the Device ID Registers of preceding devices of
the boundary scan chain.
If the Device IDs of all devices in the boundary scan chain must be captured
simultaneously, the ATmega169 must be the first device in the chain.
