[1] Select the counter clock with bits TPSC2
to TOSC0 in TCR. When an external
clock is selected, select the external
clock edge with bits CKEG1 and CKEG0
in TCR.
[2] Use bits CCLR1 and CCLR0 in TCR to
select the counter clearing source.
[3] Select the PWM mode with bits PWMB0
to PWMD0 and PWMB1 to PWMD1 in
TPMR.
[4] Set the initial output value with bits
TOB0 to TOD0 and TOB1 to TOD1 in
TOCR.
[5] Set the output level with bits POLB to
POLD in POCR.
[6] Set the cycle in GRA, and set the duty in
the other GR.
[7] Enable or disable the timer output by
TOER.
[8] Set the STR bit in TSTR to 1 and start
the counter operation.
