This active-low pin allows external hardware to
reset the device.
Programmable interrupt request.
Note: When used, this pin requires an
external 4.7K pull-up resistor.
When asserted, this pin places the device into
Hardware Power Down (HPD) mode. Refer to
Section 3.7.3, "Hardware Power-Down," on
page 28 for additional information.
