DATA
RXINI
FIFOCON
The user then reads from the FIFO and clears the FIFOCON bit (by writing a one to the FIFO
Control Clear (FIFOCONC) bit in UPCONnCLR) to free the bank. If the IN pipe is composed of
multiple banks, this also switches to the next bank. The RXINI and FIFOCON bits are updated in
accordance with the status of the next bank.
RXINI shall always be cleared before clearing FIFOCON.
The Read/Write Allowed (RWALL) bit in UPSTAn is set when the current bank is not empty, i.e.,
the software can read further data from the FIFO.

Figure 22-26. Example of an IN Pipe with 2 Data Banks
OUT packets are sent by the host. All the data can be written which acknowledges or not the
bank when it is full.
The pipe must be configured and unfrozen first.
The Transmitted OUT Data Interrupt (TXOUTI) bit in UPSTAn is set at the same time as FIFO-
CON when the current bank is free. This triggers a PnINT interrupt if the Transmitted OUT Data
Interrupt Enable (TXOUTE) bit in UPCONn is one.
TXOUTI shall be cleared by software (by writing a one to the Transmitted OUT Data Interrupt
Clear (TXOUTIC) bit in UPCONnCLR) to acknowledge the interrupt, what has no effect on the
pipe FIFO.
