DUAL 12-BIT AUTORELOAD TIMER 4 (Cont’d)
11.2.3.7 Force Update
In order not to wait for the counter
load the value into active DCRx registers, a pro-
grammable counter
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-
