16 bit mode for the SX2 device
f the CY7C68001 is set to 16 bits mode and an odd number of bytes is received over USB, what will be the sequence to read from the FIFO in the CY7C68001?
In the Wordwide mode [16 bit], for each SLWR strobe that the external master does, a word is sent on the 16 bit FIFO bus. So if the host sends 17 bytes, it will be in sets of 8 words + 1 byte and the 9th strobe of SLWR [asynchronous mode] will have the unwanted data byte [FD 8:15] which can be discarded.
