1.2.3 Active-high RST output (push-pull)
Pulses high when V
CC
drops below V
RST
, and stays high as long as V
CC
is below the reset
threshold. It remains high for t
rec
after V
CC
rises above the reset threshold.
1.2.4 Active-low RST output (open-drain with internal 5.5 kΩ pull-up) with
manual reset detect
Pulses low when V
CC
drops below V
RST
, or RST is externally pulled low for at least 1.5 µs.
It remains low for t
PBRST
after V
CC
rises above the reset threshold, or after the external
manual reset is released (see Figure 9). RST
output has an internal 5.5 kΩ pull-up resistor.
1.2.5 V
CC
Supply voltage and input for V
RST
comparator.
1.2.6 V
SS
Ground, is the reference for the power supply. It must be connected to the system ground.
