Dear... 

I set tccr0 = 0x61...

bit  | pin   | 0/1
-----------------------------
bit7 | FOC0  | 0 (MSB
bit6 | WGM00 | 1
bit5 | COM01 | 1
bit4 | COM00 | 0
bit3 | WGM01 | 0
bit2 | CS02  | 0
bit1 | CS01  | 0
bit0 | CS00  | 1 (LSB
-----------------------------
0110 0001 bin
6 1 hex
-----------------------------

so FOC0 = 0 ... not 1
and i have set COM0n[0..1]......

cheers!!!!!!!!!!!!!!!!!!!!!!!!!!!!
