Figure 14. Application: Reading words from the MQ using the EOP bit to end the read operation
During this cycle the 10G MQ
device detects the assertion of REN
During this cycle the 10G MQ
device delivers word=EOP. The
receiving device detects EOP and
de-asserts REN, However the MQ
sees a rising edge of RCLK with
REN asserted and interprets it as
another read request, and delivers
EOP +1 on the next cycle.

During this cycle the 10G MQ
device de-asserts EREN, and
maintains word=EOP + 1 to the
output data bus.
