Management of OUT endpoints
•Overview
Figure 22-19. 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.
The RXOUTI bit is set at the same time as FIFOCON when the current bank is full. This triggers
an EPnINT interrupt if the Received OUT Data Interrupt Enable (RXOUTE) bit in UECONn is
one.
RXOUTI shall be cleared by software (by writing a one to the Received OUT Data Interrupt Clear
(RXOUTIC) bit) to acknowledge the interrupt, what has no effect on the endpoint FIFO.
The user then reads from the FIFO (see
DATA)” on page
composed of multiple banks, this also switches to the next bank. The RXOUTI and FIFOCON
bits are updated in accordance with the status of the next bank.
RXOUTI shall always be cleared before clearing FIFOCON.
The RWALL bit is set when the current bank is not empty, i.e. the software can read further data
from the FIFO.
