DUAL 12-BIT AUTORELOAD TIMER 4 (Cont’d)

11.2.3.7 Force Update

In order not to wait for the counterx overflow to

load the value into active DCRx registers, a pro-

grammable counterx overflow is provided. For

both counters, a separate bit is provided which

when set, make the counters start with the over-

flow 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 re-

Figure 50. Force Overflow Timing Diagram

set by hardware after the respective counter over-

flow event has occurred.

This feature can be used at any time. All related

features such as PWM generation, Output Com-

pare, Input Capture, One-pulse (refer to Figure 15.

Dynamic DCR2/3 update in One Pulse Mode) can

be used this way.
