1 0 0 External clock: counts on TCLKA pin input
1 External clock: counts on TCLKC pin input
1 0 Internal clock: counts on ø/256
1 External clock: counts on TCLKD pin input
Note: This setting is ignored when channel 5 is in phase
counting mode.
Clock Edge
0 0 Count at rising edge
1 Count at falling edge
1 — Count at both edges
Counter Clear
Note: This setting is ignored when channel
5 is in phase counting mode.
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 operating setting is performed by setting
the SYNC bit TSYR to 1.
