8. 16-Bit Timer
Timing of Setting of Overflow Flag (OVF): OVF is set to 1 when 16TCNT overflows from
H'FFFF to H'0000 or underflows from H'0000 to H'FFFF. Figure 8.35 shows the timing.
8.5.2
If the CPU reads a status flag while it is set to 1, then writes 0 in the status flag, the status flag is
cleared. Figure 8.36 shows the timing.
