Counts on both edges.
Note: Internal clock edge selection is valid only when the input clock is ø/4 or slower. This setting
is ignored when the input clock is ø/1 or an overflow or underflow in another channel is selected.

1
TCNT cleared when other channel counters with synchronized clearing
or synchronized operation are cleared.*
Note: 1.
Sync operation is selected by setting 1 in the TSYR SYNC bit.
2.
Bit 7 of channels 1, 2, 4, and 5 is reserved. This bit always returns 0 when read, and cannot be written to.
