ISO OUT Transfers
Remote Wakeup Event
TXD Signal is Floating in Modem and Hardware Handshaking Mode.
Consequence: When this error occurs, the Host controller tries the same IN token again.
This problem can be avoided if the system guarantees that the status update can be completed
within the same frame.
Conditions:
Consider the following sequence:
Consequence: After the failure condition, the Host controller stops sending the SOF. This
causes the connected device to go into suspend state.
This problem can be avoided if the system can guarantee that no buffer underrun occurs during
the transfer.
Conditions:
When a Remote Wakeup event occurs on a downstream port, the OHCI Host controller begins
sending resume signaling to the device. The Host controller is supposed to send this resume
signaling for 20 ms. However, if the driver sets the HcControl.HCFS into USBOPERATIONAL
state during the resume event, then the Host controller terminates sending the resume signal
with an EOP to the device.
Consequence: If the Device does not recognize the resume (<20 ms) event, then the Device
remains in suspend state.
Host stack can do a port resume after it sets the HcControl.HCFS to USBOPERATIONAL.
TXD signal should be pulled up in Modem and Hardware Handshaking mode.
TXD is multiplexed with PIO which integrates a pull up resistor. This internal pull-up must be
enabled.
