mode, the PDIUSBP11A is backward compatible to PDIUSBP11. When connected to

GND, the VMO/FSEO pin takes the function of FSEO (Force SEO).

Inputs to differential driver. (Outputs from SIE).

SUSPND

I

Suspend. Enables a low power state while the USB bus is inactive. While the suspnd

pin is active it will drive the RCV pin to a logic “0” state. Both D+ and D– are tri-stated.

9

SPEED

I

Edge rate control. Logic “1” operates at edge rates for “full speed”. Logic “0” operates

edge rates for “low speed”.
