Manufacturer:NEC Description: (Reset) - The RST pin functions as a microprocessor reset signal. This pin is driven low 1) when VCC is outside of nominal limits; 2) when the watchdog timer has timed out; 3) during the power up reset period; and 4) in response to a pushbutton reset. The RST pin also functions as a pushbutton reset input. When the RST pin is driven low, the signal is debounced and timed such that a RST signal of at least 250 ms is generated. This pin has an open drain output with an internal 47 kΩ pull-up resistor. |
