Figure 16. Read Operation and Null Queue Select
NOTES:
1. The purpose of the Null queue operation is so that the user can stop reading a block (packet) of data from a queue without filling the 2 stage output pipeline with the next words
from that queue.
2. Please see Figure 17, Null Queue Flow Diagram.
Cycle:
*A* Null Q of device 0 (32nd queue) is selected, when word Wn-1 from previously selected Q1 is read.
*B*
REN is HIGH and Wn (Last Word of the Packet) of Q1 is pipelined onto the O/P register.
Note: *B* and *C* are a minimum 2 RCLK cycles between Q selects.
*C* The Null Q is seen as an empty queue on the read side, therefore Wn of Q1 remains in the O/P register and
OV goes HIGH.
*D* A new Q, Q4 is selected and the 1st word of Q4 will fall through present on the O/P register on cycle *F*.
