Auto-Reload Count Operation: Figure 12.3 shows the TCNT auto-reload operation.
TCNT Count Timing:
• Operating on internal clock
STR0–STR4
H'00000000
Internal clock
Any of five count clocks (Pck/4, Pck/16, Pck/64, Pck/256, or Pck/1024) scaled from the
peripheral module clock can be selected as the count clock by means of the TPSC2–TPSC0
bits in TCR.
Figure 12.4 shows the timing in this case.
