Description
Counter Clear 1 and 0
These bits select the method by which TCNT is
cleared.
00: Clearing is disabled
01: Cleared on compare-match A
10: Cleared on compare-match B
11: Cleared on rising edge of external reset input
Clock Select 2 to 0
The input clock can be selected from three clocks
divided from the system clock (φ). When use of an
external clock is selected, three types of count can be
selected: at the rising edge, the falling edge, and both
rising and falling edges.
