2.3 Reset

There are two kinds of resets; hardware and software. In both cases, operation is the same after the reset.

(See “Software Reset” for details of software resets.) This section explains on hardware resets.

When the supply voltage is in the range where operation is guaranteed, a reset is effected by holding the

reset pin level “L” (0.2VCC max.) for at least 20 cycles. When the reset pin level is then returned to the “H”

level while main clock is stable, the reset status is cancelled and program execution resumes from the

address in the reset vector table.

Figure 2.3.1 shows the example reset circuit. Figure 2.3.2 shows the reset sequence.
