Wifi SPWF04SA Leds question

Hi everybody!


The current datasheet ( does not give any indication to which direction that the LEDs should be going other than the name says LED Drive: module running, LED Drive: Wi-Fi Link Up, and LED Drive: power Up. This may indicate that the pin should source the LED and the reference schematic ( also shows that the pin is sourcing the LED but they do not blink when that is the case. The LEDs only seem active when the WiFi module is sinking from the LED. Is this the proper way?


Thank for the help!
