Set TIOR to make GRA an output compare
register (with output inhibited).
Set the TPC output trigger period.
Select the counter clock source with bits
TPSC2 to TPSC0 in TCR. Select the
counter clear source with bits CCLR1 and
CCLR0.
Enable the IMFA interrupt in TISRA.
Set the initial output values in the DR bits
of the input/output port pins to be used for
TPC output.
Set the DDR bits of the input/output port
pins to be used for TPC output to 1.
Set the NDER bits of the pins to be used
for TPC output to 1.
Select the 16-bit timer compare match
event to be used as the TPC output trigger
in TPCR.
Set the next TPC output values in the NDR
bits.
Set the STR bit to 1 in TSTR to start the
timer counter.
At each IMFA interrupt, set the next output
values in the NDR bits.
