Active-high RST output (push-pull)

Pulses high when VCC drops below VRST, and stays high as long as VCC is below the reset

threshold. It remains high for trec after VCC rises above the reset threshold.

Active-low RST output (open drain with internal 5.5 kΩ pull-up) with

manual reset detect

Pulses low when VCC drops below VRST, or RST is externally pulled low for at least 1.5 µs. It

remains low for tPBRST after VCC rises above the reset threshold, or after the external

manual reset is released (see Figure 10). RST output has an internal 5.5 kΩ pull-up resistor.

VCC

Supply voltage and input for VRST comparator.

VSS

Ground, is the reference for the power supply. It must be connected to the system ground.
