Universal Synchronous Asycnchronous Receiver Transmitter (USART)
UHP: Remote Wakeup Event
USART: Slave Synchronous Mode
USART: Number of Errors Register (US_NER) ISO7816 error number
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 will
remain in suspend state.
Host stack can do a port resume after it sets the HcControl, HCFS to USBOPERATIONAL.
Limitation on synchronous mode external clock is MCK/9.
None.
The Number of Errors Register always returns 0 instead of the ISO7816 error number.
It is not part of the ISO7816 protocol.
None.
