Section 10 16-Bit Timer Pulse Unit (TPU)
10.4.2
Counter Operation: When one of bits CST0 to CST5 is set to 1 in TSTR, the TCNT counter for
the corresponding channel starts counting. TCNT can operate as a free-running counter, periodic
counter, and so on.

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.
For periodic counter
operation, select the
TGR to be used as
the TCNT clearing
source with bits
CCLR2 to CCLR0 in
TCR.
Designate the TGR
selected in [2] as an
output compare
register by means of
TIOR.
Set the periodic
counter cycle in the
TGR selected in [2].
Set the CST bit in
TSTR to 1 to start
the counter
operation.
