Data Sheet
Note: Only state transitions of T3OTL which are caused by the overflows/underflows of
The maximum input frequency which is allowed in counter mode is f
To ensure that a transition of the count input signal which is applied to TxIN is correctly
recognized, its level should be held for at least 4 f
changes.
Timer Concatenation
Using the output toggle latch T3OTL as a clock source for an auxiliary timer in counter
mode concatenates the core timer T3 with the respective auxiliary timer. Depending on
which transition of T3OTL is selected to clock the auxiliary timer, this concatenation
forms a 32-bit or a 33-bit timer/counter.
l 32-bit Timer/Counter: If both a positive and a negative transition of T3OTL is used to clock the
l 33-bit Timer/Counter: If either a positive or a negative transition of T3OTL is selected to clock
The count directions of the two concatenated timers are not required to be the same.
This offers a wide variety of different configurations.
T3 can operate in timer, gated timer or counter mode in this case.
auxiliary timer, this timer is clocked on every overflow/underflow of the core timer T3. Thus, the
two timers form a 32-bit timer.
the auxiliary timer, this timer is clocked on every second overflow/underflow of the core timer T3.
This configuration forms a 33-bit timer (16-bit core timer+T3OTL+16-bit auxiliary timer).
T3 will trigger the counter function of T2/T4. Modifications of T3OTL via software
will NOT trigger the counter function of T2/T4.
