Configuring Endpoint for OUT bulk transfer

Hello,

I want send any number of bytes from host PC to the endpoint of FX2LP in full speed mode.My doubts are:

1. How can I configure the endpoints or registers so that firmware gets to know about the written bytes.

2. After reading the TRM ,I understand that bmEPxEMPTY bit will be set after the packet size is reached.Can I set packet size,if yes,How?

3. I understand that Packet end can be used for IN transfer to send any number of bytes from FW.Can it be used for OUT bulk transfer also.if yes,How?

4. Can I use PF flag to acheive this..if yes,How?

Thanks In advance.An example will be of great help.
