2.6.1 USB, When Receiving 1023 Byte Length Isochronous Frame, it Will Corrupt the 1024^th SRAM Location

When USB is configured for isochronous operation and 1023 bytes data payload size, the 1024^th RAM location directly after the endpoint RAM buffer will be corrupted.

Work Around

Allocate 1024 bytes RAM buffer when using a 1023 isochronous endpoint. This workaround is implemented in all USB software and source code from Microchip in the AVR Software Framework.
