Bits 2 to 0 Clock Select 2 to 0 (CKS2 to CKS0): Bits 2 to 0 and bit ICKS0 in TCRV1 select
the clock input to TCNTV.
Six internal clock sources divided from the system clock ( ) can be selected. The counter
increments on the falling edge.
If the external clock is selected, there is a further selection of incrementing on the rising edge,
falling edge, or both edges.
If TRGE is cleared to 0, after TCNTV is cleared it continues counting up.
