Figure 12.3 shows the low-level detection operation. Sixteen continuous low levels are sampled
with the sampling clock selected by ICSR1 to ICSR3. If even one high level is detected during this
interval, the low level is not accepted.
The timing when the high-current pins enter the high-impedance state after the sampling clock is
input is the same in both falling-edge detection and in low-level detection.

Figure 12.4 shows an example of the output-level compare operation for the combination of
TIOC3B and TIOC3D. The operation is the same for the other pin combinations.
