Timer Control
Control the source of the timer clock, the behavior of the TIO signal, and the
Timer mode of operation. Section 9.3, Operating Modes , on page 9-5
describes the timer operating modes in detail. To ensure proper operation,
the TC[3–0] bits should be changed only when the timer is disabled (that is,
when the TCSR[TE] bit is cleared).

TC2
If the clock is external, the counter is incremented by the transitions
on the TIO signal. The external clock is internally synchronized to
the internal clock, and its frequency should be lower than the
internal operating frequency divided by 4 (that is, CLK/4).
The GPIO function is enabled only if all of the TC[3–0] bits are 0.
