If Interspersed Parity is selected then during parallel programming of the flag
offset values, the device will ignore data line A8. If Non-Interspersed Parity is
selectedthendatalineA8willbecomeavalidbit. IfInterspersedParityisselected
serial programming of the offset values is not permitted, only parallel program-
ming can be done.
— SERIAL LOAD
To program the X1, X2, Y1, and Y2 registers serially, initiate a Master Reset
with FS2 LOW, FS0/SD LOW and FS1/
SEN HIGH during the LOW-to-HIGH
transitionof
MRS1andMRS2. Afterthisresetiscomplete,theXandYregister
values are loaded bit-wise through the FS0/SD input on each LOW-to-HIGH
transition of CLKA that the FS1/
SEN input is LOW. There are 44-, 48-, or 52-
bitwritesneededtocompletetheprogrammingfortheIDT723656,IDT723666,
or IDT723676, respectively. The four registers are written in the order Y1, X1,
Y2andfinally,X2. Thefirst-bitwritestoresthemostsignificantbitoftheY1register

or 1 to 8,188 (IDT723676).
When the option to program the Offset registers serially is chosen, the Port

FFA/IRA)flagremainsLOWuntilallregisterbitsarewritten.

is loaded to allow normal FIFO1 operation. The Port B Full/Input Ready (
FFC/
IRC) flag also remains LOW throughout the serial programming process, until
allregisterbitsarewritten.

of CLKC after the last bit is loaded to allow normal FIFO2 operation.
See Figure 9 timing diagram, Serial Programming of the Almost-Full Flag
and Almost-Empty Flag Offset Values after Reset (IDT Standard and FWFT
Modes).
FIFO WRITE/READ OPERATION
The state of the Port A data (A0-A35) outputs is controlled by Port A Chip
Select (
CSA)andPortAWrite/ReadSelect(W/RA). TheA0-A35outputsare
in the high-impedance state when either
CSA or W/RAisHIGH. TheA0-A35
outputs are active when both
CSA and W/RA are LOW.
Data is loaded into FIFO1 from the A0-A35 inputs on a LOW-to-HIGH
transition of CLKA when
CSA is LOW, W/RA is HIGH, ENA is HIGH, MBA is
LOW, and
FFA/IRA is HIGH. Data is read from FIFO2 to the A0-A35 outputs
by a LOW-to-HIGH transition of CLKA when
CSAisLOW,W/RAisLOW,ENA
is HIGH, MBA is LOW, and
EFA/ORA is HIGH (see Table 2). FIFO reads
and writes on Port A are independent of any concurrent Port B or Port C
operation.
The state of the Port B data (B0-B17) outputs is controlled by the Port B
Chip Select (
CSB). The B0-B17 outputs are in the high-impedance state
when
CSB is HIGH. The B0-B17 outputs are active when CSB is LOW.
