The main timer value is memorized in the IC register by a valid
input pin transition.
With a new occurrence of a capture, the value of the IC register
will be transferred to its holding register and the IC register
memorizes the new timer value.

the count register MCCNT (see
With a latching event the contents of IC registers and 8-bit
pulse accumulators are transferred to their holding registers.

into two 8-bit halves and the prescaler is bypassed. The clock
drives both halves directly.
When the high byte of timer counter TCNT ($84) overflows
from $FF to $00, the TOF flag in TFLG2 ($8F) will be set.
