Transmit Queue Length: Specifies the length of the
transmit queue.
Transmit Queue Max Length: Specifies the maximum
length of the transmit queue.
Data Bits to Extract from Received Bits: Sets the number of data bits, which can be smaller than the number of received bits. The received bit count is set in the SPI Config dialog box.
