Figure 24: No restore switch used but a green LED in a 3.3V host system. The status of the signal can also be used as input to a
host controller.
Figure 25: No restore switch used but a green LED in a 5V host system. The status of the signal can also be used as input to a
host controller.
A serial resistor to the restore switch must be used to prevent a short circuit when the GREEN/Switch-1 pin is in output HIGH state and
the switch is pressed (see Figure 26).
Sometimes, over time, switch contacts can get an oxide layer. This may cause the closed switch resistance to become too high to sink
the signal to logic LOW because the signal is internally pulled-up (see
Figure 27. The GREEN/Switch-1 pin can be left unconnected if none of its functionality is required.
