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
in TCR.
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 TMDR.
Set the CST bit in TSTR to 1 to start the count
operation.

Examples of PWM Mode Operation:
Figure 17.22 shows an example of PWM mode 1
operation.
In this example, TGRA compare match is set as the TCNT clearing source, 0 is set for the TGRA
initial output value and output value, and 1 output is set as the TGRB output value.
In this case, the value set in TGRA is used as the period, and the values set in TGRB registers as
the duty.
