Non-overlapping
pulse output
Select TGR functions
Set TGR values
Set counting operation
Select interrupt request
Set initial output data
Enable pulse output
Select output trigger
Set non-overlapping groups
Set next pulse
output data
Start counter
Compare match A?
Yes
Set next pulse
output data
Section 10 Programmable Pulse Generator (PPG)
[1] Set TIOR to make TGRA and TGRB
output compare registers (with output
disabled).
[1]
[2] Set the pulse output trigger cycle in
TGRB and the non-overlapping margin
in TGRA.
[2]
[3] Select the counter clock source with bits
[3]
TPSC2 to TPSC0 in TCR. Select the
counter clear source with bits CCLR1
and CCLR0.
[4]
[4] Enable the TGIA interrupt in TIER. The
DMAC can also be set up to transfer
[5]
data to NDR.
[6] [5] Set the initial output values in PODR.
[6] Set the bits in NDER for the pins to be
[7]
used for pulse output to 1.
[7] Select the TPU compare match event to
[8]
be used as the pulse output trigger in
PCR.
[9]
[8] In PMR, select the groups that will
operate in non-overlapping mode.
[9] Set the next pulse output values in NDR.
[10]
[10] Set the CST bit in TSTR to 1 to start the
No
TCNT counter.
[11] At each TGIA interrupt, set the next
output values in NDR.
