11.6.3 Conflict
between
TCMICR Read and Input Capture
When operation is in timer mode and the corresponding input capture signal is detected during
reading of TCMICR, the input capture signal is delayed by one system clock (
φ
). Figure 11.15
shows the timing of this conflict.

11.6.4
Conflict between Edge Detection in Cycle Measurement Mode and Writing to
TCMMLCM or TCMMINCM
If the selected edge of TCMCYI is detected in the second half of a cycle of writing to the register
(TCMMLCM or TCMMINCM) in cycle measurement mode, the detected edge signal is delayed
by one cycle of the system clock (
φ
).
Figure 11.16 shows the timing of this conflict.
