2.3 Reset
There are three types of resets: a hardware reset, a software reset, and an watchdog timer reset.
2.3.1 Hardware Reset
____________
A reset is applied using the RESET pin. When an “L” signal is applied to the RESET pin while the power
supply voltage is within the recommended operating condition, the pins are initialized (see Table 2.3.1).
____________
The oscillation circuit is initialized and the main clock starts oscillating. When the input level at the RESET
pin is released from “L” to “H”, the CPU and SFR are initialized, and the program is executed starting from
____________
the address indicated by the reset vector. The internal RAM is not initialized. If the RESET pin is pulled “L”
while writing to the internal RAM, the internal RAM becomes indeterminate.
Figure 2.3.1 shows the example reset circuit. Figure 2.3.2 shows the reset sequence. Table 2.3.1 shows
____________
the statuses of the other pins while the RESET pin is “L”. Figure 2.3.3 shows the CPU register status after
reset. Refer to “SFR” for SFR status after reset.
1. When the power supply is stable
____________
(1) Apply an “L” signal to the RESET pin.
(2) Supply a clock for 20 cycles or more to the XIN pin.
____________
(3) Apply an “H” signal to the RESET pin.
2. Power on
____________
(1) Apply an “L” signal to the RESET pin.
(2) Let the power supply voltage increase until it meets the recommended operating condition.
(3) Wait td(P-R) or more until the internal power supply stabilizes.
(4) Supply a clock for 20 cycles or more to the XIN pin.
____________
(5) Apply an “H” signal to the RESET pin.
