12.6.3 Conflict
between
Input Capture and TDPICR Read
When the corresponding input capture signal is detected during reading of TDPICR in timer mode,
the input capture signal is delayed by one cycle of the system clock (
φ
). Figure 12.15 shows the
timing of this conflict.

12.6.4
Conflict between Edge Detection in Cycle Measurement Mode and Writing to the
Upper Limit or Lower Limit Register
If the edge of TDPCYI is detected in the second half of a cycle of writing to any of the upper
limit/lower limit registers (TDPPDMX, TDPPDMN, TDPWDMX, and TDPWDMN) in cycle
measurement mode, the detected edge signal is delayed by one cycle of the system clock (
φ
).
Figure 12.16 shows the timing of this conflict.
