Section 11 16-Bit Free-Running Timer
11.6
Application programmers should note that the following types of contention can occur in the free-
running timer.
Contention between FRC Write and Clear: If an internal counter clear signal is generated
during the state after an FRC write cycle, the clear signal takes priority and the write is not
performed.
Figure 11.18 shows this type of contention.
