and FIFO
B
initially empty, SO
A
held HIGH in anticipation of data
Load one word into FIFO

; SI pulse applied, results in DIR pulse
Data-out
A
/data-in
B
transition; valid data arrives at FIFO
A
output stage after a specified delay of the DOR flag,
meeting data input set-up requirements of FIFO
B
DOR
A
and SI
B
pulse HIGH; (ripple through delay after SI
A
LOW) data is unloaded from FIFO
A
as a result of the data
output ready pulse, data is shifted into FIFO
B
DIR
B
and SO
A
go LOW; flag indicates input stage of FIFO
B
is busy, shift-out of FIFO
A
is complete
DIR
B
and SO
A
go HIGH automatically; the input stage of FIFO
B
is again able to receive data, SO is held HIGH in
anticipation of additional data
DOR
B
goes HIGH; (ripple through delay after SI
B
LOW) valid data is present one propagation delay later at the FIFO
B
output stage.
