5. Resets
Hardware reset, software reset, watchdog timer reset, and oscillation stop detection reset are available to
reset the MCU.
5.1 Hardware Reset
Figure 5.1 Example Reset Circuit
The MCU resets pins, the CPU and SFR by setting the RESET pin. If the supply voltage meets the
recommended operating conditions, the MCU resets all pins when an “L” signal is applied to the RESET pin
(see Table 5.1 Pin Status When RESET Pin Level is “L”). The oscillation circuit is also reset and the main
clock starts oscillation. The MCU resets the CPU and SFR when the signal applied to the RESET pin
changes low (“L”) to high (“H”). The MCU 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 undefined state.
Figure 5.1 shows an Example Reset Circuit. Figure 5.2 shows a Reset Sequence. Table 5.1 lists the Pin
States when RESET Pin Level is “L”.
5.1.1 Reset on a Stable Supply Voltage
5.1.2 Power-on Reset
(1) Apply “L” to the RESET pin
(2) Apply 20 or more clock cycles to the XIN pin
(3) Apply “H” to the RESET pin
(1) Apply “L” to the RESET pin
(2) Raise the supply voltage to the recommended operating level
(3) Insert td(P-R) ms as wait time for the internal voltage to stabilize
(4) Apply 20 or more clock cycles to the XIN pin
(5) Apply “H” to the RESET pin
