AVR-Chat

Thank you so much John. 

Using the LDS instruction my problem was solved.
Absolutely the operand was out of range because in the ATmega169P 
the address is higher than 63 for the timer1 counter registers wish is not supported by the "IN" instruction.

Reference:Page 79, AVR instruction set.

 Depending on which processor you are using, TCNT1 could be
 memory mapped and therefore you need to use LDS and STS
 instead of IN/OUT.
 
 You can also use a macro from AVR001 LOAD and STORE and it
 will automatically switch in the correct instruction.
