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” (0.2V
level while main clock is stable, the reset status is cancelled and program execution resumes from the
address in the reset vector table.
Figure 4.1 shows the example reset circuit. Figure 4.2 shows the reset sequence.
