PACKET
SHORT
Set by hardware when the current bank is ready to accept a new IN packet. This triggers an EPXINT interrupt if
TXINE = 1.
Shall be cleared by software (by setting the TXINIC bit) to acknowledge the interrupt and to send the packet.
Set by hardware at the same time as FIFOCON when the current bank is free. This triggers an EPXINT interrupt if
TXINE = 1.
Shall be cleared by software (by setting the TXINIC bit) to acknowledge the interrupt, what has no effect on the end-
point FIFO.
The software then writes into the FIFO and clears the FIFOCON bit to allow the USB controller to send the data. If
the IN endpoint is composed of multiple banks, this also switches to the next bank. The TXINI and FIFOCON bits are
updated by hardware in accordance with the status of the next bank.
TXINI shall always be cleared before clearing FIFOCON.
Set by hardware when the current bank contains a bulk OUT packet (data or status stage). This triggers an EPXINT
interrupt if RXOUTE = 1.
