This active low signal allows external hardware to
reset the device. The device also contains an
internal power-on reset circuit. Thus, this signal
may be left unconnected if an external hardware
reset is not needed. When used, this signal must
adhere to the reset timing requirements as detailed
in the
Strap Timing," on page
