[Lower timer TAA0]
This section explains an operation of connecting two channels of TAA in cascade to form a 32-bit capture timer.
For cascade connection, the “free-running timer mode” must be set and all the capture/compare registers must be
Combinations of TAA channels that can be connected in cascade are shown in the following table.
In the following example, TAA0 is used as the lower timer (master timer) and TAA1 is used as the higher timer
