CURRBK: Current Bank
NBUSYBK: Number of Busy Banks
DTSEQ: Data Toggle Sequence
SHORTPACKET: Short Packet Interrupt
STALLEDI: STALLed Interrupt
This bit is set for non-control endpoints, to indicate the current bank:
This field may be updated one clock cycle after the RWALL bit changes, so the user should not poll this field as an interrupt bit.
This field is set to indicate the number of busy banks:
For IN endpoints, it indicates the number of banks filled by the user and ready for IN transfer. When all banks are free, this
For OUT endpoints, it indicates the number of banks filled by OUT transactions from the host. When all banks are busy, this
When the FIFOCON bit is cleared (by writing a one to the FIFOCONC bit) to validate a new bank, this field is updated two or
An EPnINT interrupt is triggered if:
- for IN endpoint, NBUSYBKE is one and all the banks are free.
- for OUT endpoint, NBUSYBKE is one and all the banks are busy.
This field is set to indicate the PID of the current bank:
For IN transfers, it indicates the data toggle sequence that will be used for the next packet to be sent. This is not relative to the
For OUT transfers, this value indicates the last data toggle sequence received on the current bank.
By default DTSEQ is 0b01, as if the last data toggle sequence was Data1, so the next sent or expected data toggle sequence
This bit is set for non-control OUT endpoints, when a short packet has been received.
This bit is set for non-control IN endpoints, a short packet is transmitted upon ending a DMA transfer, thus signaling an end of
This triggers an EPnINT interrupt if SHORTPACKETE is one.
This bit is cleared when the SHORTPACKETC bit is written to one. This will acknowledge the interrupt.
This bit is set to signal that a STALL handshake has been sent. To do that, the software has to set the STALLRQ bit (by writing a
