Hardware reset 1, software reset, and watchdog timer reset are available to reset the microcomputer.
Pins, the CPU and SFRs are reset by setting the RESET pin. If the supply voltage meets the recommended
operating conditions, all pins are reset when a low-level ("L") signal is applied to the RESET pin (see Table
5.1). The oscillation circuit is also reset and the main clock starts oscillating. The CPU and SFR are reset
when the signal applied to the RESET pin changes "L" to high level ("H"). The microcomputer executes the
program in an address indicated by the reset vector. The internal RAM is not reset. When an "L" signal is
applied to the RESET pin while writing data to the internal RAM, the internal RAM is in an indeterminate
state.
Figure 5.1 shows an example of the reset circuit. Figure 5.2 shows a reset sequence. Table 5.1 lists pin
states while the RESET pin is held "L".
