Timing System
9.4.1 Timer Counter Register
Technical Data
188
Address: $000E — TCNT (High)
Address: $000F — TCNT (Low)
TCNT reflects the current value in the free-running counter. Input
capture functions use this number to mark the time of an external event,
and output compare functions use it to determine the time at which to
generate an event.
In normal modes, TCNT is a read-only register. Writes to TCNT in
normal modes have no effect. TCNT can be read and written in special
modes.
