• Description: (HD64 Series) Hitachi Single-Chip Microcomputer
• Manufacturer: Hitachi Semiconductor

Timing of Setting of IMFA and IMFB by Input Capture: IMFA and IMFB are set to 1 by an
input capture signal. The TCNT contents are simultaneously transferred to the corresponding
general register. Figure 10-58 shows the timing.
Timing of Setting of Overflow Flag (OVF): OVF is set to 1 when TCNT overflows from H'FFFF
to H'0000 or underflows from H'0000 to H'FFFF. Figure 10-59 shows the timing.
