TXOUTI
FIFOCON
TXOUTI
FIFOCON
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.
The user then writes into the FIFO (see
DATA)” on page
OUT pipe is composed of multiple banks, this also switches to the next bank. The TXOUTI and
FIFOCON bits are updated in accordance with the status of the next bank.
TXOUTI shall always be cleared before clearing FIFOCON.
The UPSTAn.RWALL bit is set when the current bank is not full, i.e., the software can write fur-
ther data into the FIFO.
Note that if the user decides to switch to the Suspend state (by writing a zero to the
UHCON.SOFE bit) while a bank is ready to be sent, the USBB automatically exits this state and
the bank is sent.
