QUEUE DESCRIPTION
CONFIGURATION OF THE IDT MULTI-QUEUE FLOW-CONTROL DEVICE
trol devices can be configured in distinct modes, namely Packet mode, FIFO
flag (EF) signaling. EF is an active LOW signal. When EF is LOW it signifies the
selected (present) queue is empty. On the write port, signal FF/IR is configured
signaling. OR is an active LOW signal. When OR is HIGH, it signifies there is no
available word to read. On the write port, signal FF/IR is configured for input
