UPINRQx.INRQ field is limited to 8-bits
In Host mode, when using the UPINRQx.INRQ feature together with the multi-packet mode
to launch a finite number of packet among multi-packet, the multi-packet size (located in the
descriptor table) is limited to the UPINRQx.INRQ value multiply by the pipe size.
Fix/Workaround
UPINRQx.INRQ value shall be less than the number of configured multi-packet.
Clearing the Watchdog Timer (WDT) counter in second half of timeout period will
issue a Watchdog reset
If the WDT counter is cleared in the second half of the timeout period, the WDT will immedi-
ately issue a Watchdog reset.
Fix/Workaround
Use twice as long timeout period as needed and clear the WDT counter within the first half
of the timeout period. If the WDT counter is cleared after the first half of the timeout period,
you will get a Watchdog reset immediately. If the WDT counter is not cleared at all, the time
before the reset will be twice as long as needed.
