Management of OUT endpoints
•Detailed description
•Overview
The data is written, following the next flow:
If the endpoint uses several banks, the current one can be written while the previous one is
being read by the host. Then, when the user clears FIFOCON, the following bank may already
be free and TXINI is set immediately.
An “Abort” stage can be produced when a zero-length OUT packet is received during an IN
stage of a control or isochronous IN transaction. The Kill IN Bank (KILLBK) bit in UECONn is
used to kill the last written bank. The best way to manage this abort is to apply the algorithm rep-
resented on
Figure 26-18. Abort Algorithm
OUT packets are sent by the host. All the data can be read which acknowledges or not the bank
when it is empty.
The endpoint must be configured first.
• When the bank is empty, TXINI and FIFOCON are set, what triggers an EPnINT interrupt if
• The user acknowledges the interrupt by clearing TXINI.
• The user writes the data into the current bank by using the USB Pipe/Endpoint nFIFO Data
• The user allows the controller to send the bank and switches to the next bank (if any) by
