How to reset/flush the endpoint FIFO buffer of FX2LP?
Last Updated: 12/19/2008
Q) How to reset/flush the endpoint FIFO buffer of FX2LP?
A) Endpoint buffer can be flushed using the register FIFORESET. Write 0x80 to this register to NAK all transfers from the host, then write 0x02, 0x04, 0x06, or 0x08 to reset an individual endpoint FIFO (i.e., to restore endpoint FIFO flags and byte counts to their default states), then write 0x00 to restore normal operation.
