Bulk/Interrupt IN Transactions
in Standard Mode
Figure 61. Bulk/Interrupt IN Transactions in Standard Mode
An endpoint will be first enabled and configured before being able to send Bulk or Inter-
rupt packets.
The firmware will fill the FIFO with the data to be sent and set the TXRDY bit in the UEP-
STAX register to allow the USB controller to send the data stored in FIFO at the next IN
request concerning this endpoint. To send a Zero Length Packet, the firmware will set
the TXRDY bit without writing any data into the endpoint FIFO.
Until the TXRDY bit has been set by the firmware, the USB controller will answer a NAK
handshake for each IN requests.
To cancel the sending of this packet, the firmware has to reset the TXRDY bit. The
packet stored in the endpoint FIFO is then cleared and a new packet can be written and
sent.
When the IN packet has been sent and acknowledged by the Host, the TXCMPL bit in
the UEPSTAX register is set by the USB controller. This triggers a USB interrupt if
enabled. The firmware will clear the TXCMPL bit before filling the endpoint FIFO with
new data.
The firmware will never write more bytes than supported by the endpoint FIFO.
All USB retry mechanisms are automatically managed by the USB controller.
