Select the counter clock with bits TPSC2 to

TPSC0 in TCR. At the same time, select the

input clock edge with bits CKEG1 and CKEG0

Use bits CCLR2 to CCLR0 in TCR to select the

TGR to be used as the TCNT clearing source.

Use TIOR to designate the TGR as an output

compare register, and select the initial value and

output value.

Set the cycle in the TGR selected in [2], and set

the duty in the other the TGR.

Select the PWM mode with bits MD3 to MD0 in

Set the CST bit in TSTR to 1 start the count
