External Bus Interface (EBI)
Peripheral I/O Controller (PIO)
Real Time Clock (RTC)
USB High Speed Host Port (UHPHS)
EBI: Data lines are Hi-Z after reset
PIOD: PD[18:15] Reset State is not correct
RTC: Interrupt Mask Register cannot be used
UHPHS: Packet Loss Issue in the UTMI Transceivers
Data lines are Hi-Z after reset.
Data line pull-downs are to be activated by software at reset on data bus.
PD[18:15] reset state (input pull-down on peripheral A) is incoherent with the external boot fea-
ture. External boot requires that PD[18:15] be in peripheral mode on peripheral B. The boot
functionality is assured thanks to the pull down, but the software must reconfigure PIOD after
reset.
The software must reconfigure PIOD after reset.
Interrupt Mask Register reading always returns 0.
None
High-Speed USB Host may lose incoming packets when connected to an external USB Hub.
A high data transfer error rate has been observed on the High-Speed USB Host interface when
connected to an external USB Hub. The USB remains functional but the errors may require a
reset of the USB interface to recover.
The Full-Speed USB Host operation is not affected by this problem.
A workaround consists of implementing a timeout on the USB communication using one of the
timers in the device and trigger a reset of the USB Host interface via software and restart the
communication. The impact of the workaround on the data rate is dependent on the error rate
observed in the application but can be such that streaming data at high rates becomes
impractical.
