MODE [28:27]: Timer Operating Mode
PRESCALE [7:0]
Clock input is divided by PRESCALE + 1 before it is fed to the counter (here PRESCALE is considered
as a decimal number). If PRESCALE = 0, then there is no scaling.
Timer Initial Count Register 0 (TICR0)
Timer Initial Count Register 1 (TICR1)
TIC [23:0]: Timer Initial Count
This is a 24-bit value representing the initial count. Timer will reload this value whenever the counter is
decremented to zero.

The timer is operating in the one-shot mode. The associated interrupt signal is
generated once (if IE is enabled) and CE is automatically cleared then.
The timer is operating in the periodic mode. The associated interrupt signal is
generated periodically (if IE is enabled).
The timer is operating in the toggle mode. The associated interrupt signal is
changing back and forth (if IE is enabled) with 50% duty cycle.
