11.1.2.3 Timer Concatenation
Using the toggle bit T6OTL as a clock source for the auxiliary timer in counter mode
concatenates the core timer T6 with the auxiliary timer. Depending on which transition of
T6OTL is selected to clock the auxiliary timer, this concatenation forms a 32-bit or a 33-
bit timer / counter.
32-bit Timer/Counter: If both a positive and a negative transition of T6OTL is used to
clock the auxiliary timer, this timer is clocked on every overflow/underflow of the core
timer T6. Thus, the two timers form a 32-bit timer.
33-bit Timer/Counter: If either a positive or a negative transition of T6OTL is selected to
clock the auxiliary timer, this timer is clocked on every second overflow/underflow of the
core timer T6. This configuration forms a 33-bit timer (16-bit core timer+T6OTL+16-bit
auxiliary timer).
The count directions of the two concatenated timers are not required to be the same.
This offers a wide variety of different configurations.
