11.3.1
The TCR registers are 8-bit readable/writable registers that control the TCNT operation for each
channel. The MTU2 has a total of five TCR registers, one each for channels 0 to 4. TCR register
settings should be conducted only when TCNT operation is stopped.

Description
Counter Clear 0 to 2
These bits select the TCNT counter clearing source.
See tables 11.4 and 11.5 for details.
Clock Edge 0 and 1
These bits select the input clock edge. When the input
clock is counted using both edges, the input clock
period is halved (e.g. Pφ/4 both edges = Pφ/2 rising
edge). If phase counting mode is used on channels 1
and 2, this setting is ignored and the phase counting
mode setting has priority. Internal clock edge selection
is valid when the input clock is Pφ/4 or slower. When
Pφ/1, or the overflow/underflow of another channel is
selected for the input clock, although values can be
written, counter operation compiles with the initial value.
00: Count at rising edge
01: Count at falling edge
1x: Count at both edges
Time Prescaler 0 to 2
These bits select the TCNT counter clock. The clock
source can be selected independently for each channel.
See tables 11.6 to 11.9 for details.
