Note:
Force update
In order not to wait for the counter
programmable counter
which when set, make the counters start with the overflow value, i.e. FFFh. After overflow,
the counters start counting from their respective auto reload register values.
These bits are FORCE1 and FORCE2 in the ATCSR2 register. FORCE1 is used to force an
overflow on Counter 1 and, FORCE2 is used for Counter 2. These bits are set by software
and reset by hardware after the respective counter overflow event has occurred.
This feature can be used at any time. All related features such as PWM generation, Output
Compare, Input Capture, One-pulse (refer to

Table 35.
Interrupts
Table 36.
The AT4 IC is connected to an interrupt vector. The OVF event is mapped on a separate
vector (see Interrupts chapter).
They generate an interrupt if the enable bit is set in the ATCSR register and the interrupt
mask in the CC register is reset (RIM instruction).
