Reset

Introduction

The reset sources are: Power Management, Hardware Watchdog, PCA Watchdog and

Reset input.

Figure 9. Reset schematic

Reset Input

The Reset input can be used to force a reset pulse longer than the internal reset con-

trolled by the Power Monitor. RST input has a pull-down resistor allowing power-on

reset by simply connecting an external capacitor to VCC as shown in Figure 10. Resistor

value and input characteristics are discussed in the Section “DC Characteristics” of the

AT89C51RD2/ED2 datasheet.
