Time Prescaler
0 0 0 Internal clock: counts on φ/1
1 Internal clock: counts on φ/4
1 0 Internal clock: counts on φ/16
1 Internal clock: counts on φ/64
1 0 0 External clock: counts on TCLKA pin input
1 External clock: counts on TCLKB pin input
1 0 Internal clock: counts on φ/256
1 Counts on TCNT2 overflow/underflow
Note: This setting is ignored when channel 1 is in phase
counting mode.
Clock Edge*
0 0 Count at rising edge
1 Count at falling edge
1 ⎯ Count at both edges
Note: * This setting is ignored when channel
1 is in phase counting mode.
The internal clock edge selection is
valid when the input clock is φ/4 or slower. This setting
is ignored if φ/1 or overflow/underflow on another channel
is selected as the input clock.
Counter Clear
0 0 TCNT clearing disabled
1 TCNT cleared by TGRA compare match/input capture
1 0 TCNT cleared by TGRB compare match/input capture
1 TCNT cleared by counter clearing for another channel
performing synchronous clearing/synchronous operation*
Note: * Synchronous operation setting is performed by setting
the SYNC bit in TSYR to 1.
