Bits 4 and 3—Clock Edge 1 and 0 (CKEG1, CKEG0): These bits select the input clock edge. When the input clock is
counted using both edges, the input clock period is halved (e.g. ø/4 both edges = ø/2 rising edge). If phase counting mode
is used on channels 1, 2, 4, and 5, this setting is ignored and the phase counting mode setting has priority.
Note: Internal clock edge selection is valid when the input clock is ø/4 or slower. This setting is ignored if the input clock is
Bits 2 to 0—Time Prescaler 2 to 0 (TPSC2 to TPSC0): These bits select the TCNT counter clock. The clock source can
be selected independently for each channel. Table 10-4 shows the clock sources that can be set for each channel.
