[1] 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.
[2] Use bits CCLR2 to CCLR0 in TCR to select the
TGR to be used as the TCNT clearing source.
[3] Use TIOR to designate the TGR as an output
compare register, and select the initial value and
output value.
[4] Set the period in the TGR selected in [2], and
set the duty in the other TGR.
[5] Select the PWM mode with bits MD3 to MD0 in
