General Purpose Input/Output for DS3170
The DS3170 SCT has an 8-bit port that can be bit configured as either general-purpose I/O or specific alarms, a
TEMI input, or PMU input. Refer to the DS3170 data sheet for specific questions about the operation of the
DS3170 GPIO port.
Each GPIO pin has two types of inputs and an LED for easy identification of the pin’s state. The first input type for
the GPIO port is an 8-bit switch (SW4). Each pin on SW4 corresponds to the bit in the GPIO. When the switch is in
the “On” position, the pin for the switch is grounded and provides logic 0 to the port. When the switch is in the “Off”
position, the pin for the switch floats to VDD and provides logic 1 to the port.
The second input type for the GPIO port is a straight 10-pin header (J7). This can be simply a monitoring pin for the
GPIO port or used as input stimulus. Note: If you plan to drive a bit to a value other than GND, the GPIO bit in
SW4 must be in the “Off” position. See the DS3170DK schematic for questions on the connection of the GPIO port.
Table 4 provides a description of pin out of SW4 and J7.

TEMI and PMU Inputs
GPIO Bit 6 and GPIO Bit 8 can be configured to be the TEMI and PMU inputs respectively. A pushbutton (SW5)
and 3-position jumper (JP6) are available to provide a glitch-free input to either of these inputs. Note: When using
the pushbutton (SW5) and 3-position jumper (JP6) as an input to the GPIO pins, you must have the appropriate
switch in SW4 in the “Off” position.
