Manual Reset
The manual reset input (MR) allows the user to trigger a
reset by using a push-button switch. The MR input is an
active low debounced input. By connecting a push-button
directly from MR to ground, the designer adds manual
system reset capability (see Figure 3). Reset is asserted if
the MR pin is pulled low to less than 100mV for 10µs or
longer while the push-button is closed. After MR is released,
the reset outputs remain asserted for tPOR (200ms) and then
released.

Using the ISL88016/17EVAL1Z Platform
The ISL88016/17EVAL1Z platform is provided with both an
ISL88016 in the top and an ISL88017 in the bottom
positions. Each IC is default programmed to VSET1, VSET2
and VSET3 = FLOAT but provided with jumpers to change
the Vth level by individually connecting the three VSET pins
to either VDD (1) or GND (0). To the left of the circuits is a
VSET programming table for easy reference. Provide
adequate bias to VDD to deassert RESET signal. See
Figure 4 for the ISL88016/17EVAL1Z schematic and
Figure 5 for its photograph.
