• Manufacturer: Hitachi Semiconductor

Figure 7-7 shows the timing when the output is set to toggle on compare-match A.
(4) Timing of Compare-Match Clear: Depending on the CCLR1 and CCLR0 bits in the TCR,
the timer counter can be cleared when compare-match A or B occurs. Figure 7-8 shows the timing
of this operation.
7.3.3 External Reset of TCNT
When the CCLR1 and CCLR0 bits in the TCR are both set to “1,” the timer counter is cleared on
the rising edge of an external reset input. Figure 7-9 shows the timing of this operation. The timer
reset pulse width must be at least 1.5 system clock periods.
