11.2.1
TCNT is an 8-bit readable and writable up-counter.
Note: The method for writing to TCNT is different from that for general registers to prevent
When the TME bit is set to 1 in TCSR, TCNT starts counting pulses generated from an internal
clock source selected by bits CKS2 to CKS0 in TCSR. When the count overflows (changes from
H'FF to H'00), the OVF bit is set to 1 in TCSR. TCNT is initialized to H'00 by a reset and when
the TME bit is cleared to 0.

inadvertent overwriting. For details see section 11.2.4, Notes on Register Access.
2. Write word data starting at this address.
3. Only 0 can be written in bit 7, to clear the flag.
