Section 11 16-Bit Timer Pulse Unit (TPU)
11.3.1
The TCR registers control the TCNT operation for each channel. The TPU has a total of six TCR
registers, one for each channel. TCR register settings should be made only when TCNT operation
is stopped.

Description
Counter Clear 2 to 0
These bits select the TCNT counter clearing
source. See tables 11.4 and 11.5 for details.
Clock Edge 1 and 0
These bits select the input clock edge. When the
input clock is counted using both edges, the input
clock period is halved (e.g. φ/4 both edges = φ/2
rising edge). If phase counting mode is used on
channels 1, 2, 4, and 5, this setting is ignored and
the phase counting mode setting has priority.
Internal clock edge selection is valid when the
input clock is φ/4 or slower. This setting is ignored
if the input clock is φ/1, or when
overflow/underflow of another channel is selected.
00: Count at rising edge
01: Count at falling edge
1x: Count at both edges

Time Prescaler 2 to 0
These bits select the TCNT counter clock. The
clock source can be selected independently for
each channel. See tables 11.6 to 11.11 for details.
