Complete all steps discover to connect and configure a device. Write USB_ADDR with the
address of the target device.
Write the ENDPT0 to 0x1D to enable transmit and receive transfers with handshaking enabled.
Setup the Even TX EP0 BDT to transfer up to 64 bytes.
Set the device address of the target device in USB_ADDR.
Write USB_TOKEN with an OUT token to the desired endpoint. The write to this register will
trigger the USB block transmit state machines to begin transmitting the TOKEN and the data.
Setup the Odd TX EP0 BDT to transfer up to 64 bytes.
Write USB_TOKEN with an OUT.
Wait for USB_ISTAT.TDONE to be set, indicating the transfer has completed. If the target
NAKed, the controller retries indefinitely without unless USB_EP0_CTRL.RETRY_DIS is set. If
set, the handshake (ACK, NAK, STALL or ERROR) is returned in the BDT PID field. If a
STALL, the packet must be de-queued and the error condition in the device cleared. If a
RESET occurs the target has detached.
Once USB_ISTAT.TDONE set, the BDTs can be examined and the next packet queued.
Action
If ID Interrupt, type A cable plugged in. Goto A_IDLE
If BSESSV Interrupt, “A” device has turned on VBUS and will begin a session, turn on DPH and
goto B_PERIPHERAL
If “B” application wants the bus and Bus is Idle for 2ms and BSESSE set, “B” device can perform
an SRP, Pulse CHRG_VBUS Pulse DPH 5-10 ms and goto B_SRP_INIT
If ID Interrupt or SRP Done (SRP must be done in less than 100 ms), goto B_IDLE
If HNP enabled and the bus is suspended and “B” wants the bus, the “B” device can become the
host, turn off DPH and goto WAIT_ACON
If “A” connects, that is, an attach interrupt is received, turn on host mode, and goto B_HOST
If ID Interrupt or BSESSV Interrupt, if the cable changes or if VBUS goes away, host doesn’t
support us, goto B_IDLE
If 3.125 ms expires or if a Resume occurs, goto B_PERIPHERAL
If ID Interrupt or BSESSV Interrupt. if cable changes or V
goto B_IDLE.
If “B” application is done or “A” disconnects, goto B_PERIPHERAL
