Timing of TGF Flag Setting by Compare Match: Figure 16.12 shows the timing of setting of
the TGF flag in the timer status register (TSR) on a compare match between TCNT and TPDR,
and the timing of the TGI interrupt request signal. The timing is the same for a compare match
between TCNT and 2Td.
Status Flag Clearing Timing: A status flag is cleared when the CPU reads 1 from the flag, then 0
is written to it. When the DTC controller is activated, the flag is cleared automatically. Figure
16.13 shows the timing of status flag clearing by the CPU, and figure 16.14 shows the timing of
status flag clearing by the DTC.
