Contention between Buffer Register Write and Input Capture: If the input capture signal is generated in the T
a buffer write cycle, the buffer operation takes precedence and the write to the buffer register is not performed.
Figure 10-55 shows the timing in this case.
Contention between Overflow/Underflow and Counter Clearing: If overflow/underflow and counter clearing occur
simultaneously, the TCFV/TCFU flag in TSR is not set and TCNT clearing takes precedence.
Figure 10-56 shows the operation timing when a TGR compare match is specified as the clearing source, and H'FFFF is
set in TGR.
