[1] In the case of unit 0, set TIOR of the TPU to make
TGRA an output compare register (output disabled).
In the case of unit 1, set TIOR of the TPU to make
TGRA an output compare register (toggle output).
[2] Set the PPG output trigger period.
[3] Select the counter clock source with the TPSC[2:0] bits
in TCR. Select the counter clear source with the
CCLR[2:0] bits.
[4] Enable the TGIA interrupt in TIER.
The DTC or DMAC can also be set up to transfer data
to NDR.
[5] Set the initial output values in PODR.
[6] Set the bits for the pins to be used for pulse output
to 1.
[7] Select the TPU compare match event to be used as
the output trigger in PTRSLR and PCR.
[8] Set the next pulse output values in NDR.
[9] Set the CST bit in TSTR to 1 to start the TCNT
counter.
[10] At each TGIA interrupt, set the next output values in
NDR.
