As described above, T12 can operate in Edge-Aligned mode or Center-Aligned mode. In
both modes, a certain set of ‘counting rules’ determine the behavior of the T12 counter.
The counting rules lead to a behavior in Edge-Aligned mode as illustrated in
Figure 18-5.
In the Center-Aligned mode (T12 counts up and down), the counting rules lead to the
behavior shown in Figure 18-6.
T12 in Edge-Aligned Mode:
• With the next clock of f_T12 the counter is reset to zero when a Period-Match is
detected. The counting direction is always upwards (CDIR = 0).
