Touch Screen (TSADCC)
USB High Speed Host Port (UHPHS)
USB High Speed Host Port (UHPHS) and Device Port (UDPHS)
TSADCC: Pen detect accuracy is not good
UHPHS: Packet Loss Issue in the UTMI Transceivers
UHPHS/UDPHS: USB does not start after power-up
None
Depending on LCD panels, the pen detect is noisy, leading to an unpredictable behavior.
An additional resistor solves the problem. Its value (between 100 kOhm and 250 kOhm) is to be
tuned for the LCD panel.
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.
The USB may not start properly at first use after power-up.
Booting out of the internal ROM fixes this issue because the workaround below is applied in the
ROM Code.
