NOTES:
1.
2.
Wait on Rx. Receiver FIFO empty.
Timing is illustrated and referenced to the WRN and RDN inputs. The device may also be operated with CEN as the ‘strobing’ input. CEN and RDN
(also CEN and WRN) are ANDed internally. As a consequence, the signal asserted last initiates the cycle and the signal negated first terminates the
cycle.
