SIGNALDESCRIPTIONS
RESET
The IDT723616 is reset by taking the reset (
RST) input LOW for at least
four Port A clock (CLKA), four Port B clock (CLKB) and four Port C clock
(CLKC) LOW-to-HIGH transitions. The reset input can switch asynchro-
nously to the clocks. A device reset initializes the internal read and write
pointers of each FIFO and forces the full flags (
FFA, FFC) LOW, the empty
flags (
EFA, EFB) LOW, the Almost-Empty flags (AEA, AEB) LOW and the
Almost-Full flags (
AFA, AFC) HIGH. After a reset, FFA is set HIGH after
two LOW-to-HIGH transitions of CLKA and FFC is set HIGH after two
LOW-to-HIGH transitions of CLKC. The device must be reset after power
up before data is written to its memory.
A LOW-to-HIGH transition on the
RST input loads the Almost-Full and
Almost-Empty Offset register (X) with the values selected by the flag-
select (FS0, FS1) inputs. The values that can be loaded into the registers
are shown in Table 1.
TABLE 2 — PORT-A ENABLE FUNCTION TABLE
FIFO WRITE/READ OPERATION
The state of Port A data A0-A35 outputs is controlled by the Port A chip
select (
CSA)andthePortAwrite/readselect(W/RA).TheA0-A35outputsare
in the high-impedance state when either
CSA or W/RA is HIGH. The A0-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, and FFA is HIGH. Data is read
fromFIFO2totheA0-A35outputsbyaLOW-to-HIGHtransitionofCLKAwhen
CSA is LOW, W/
RA is LOW, ENA is HIGH, and EFA is HIGH (see Table 2).
The state of the Port B data (B0-B17) outputs is controlled by Port B read
select (RENB). The B0-B17 outputs are in the high-impedance state when
REN is LOW. The B0-B17 outputs are active when REN IS HIGH. Data is
read from FIFO1 to the B0-B17 outputs by a LOW-to-HIGH transition of
CLKB when RENB is HIGH,
EFB is HIGH, and either SIZ0 or SIZ1 is LOW
(see Table 3).
Data is loaded into FIFO2 from the C0-C17 inputs on a LOW-to-HIGH
transition of CLKC when WENC is HIGH,
FFC is HIGH, and either SIZ0 or
SIZ1 is LOW (see Table 4).
ThesetupandholdtimeconstraintstothePortClocksforthePortAchipselect
(CSA) and write/read selects (W/
RA, RENB, WENC) are only for enabling
write and read operations and are not related to high-impedance control of the
data outputs. If a port enable is LOW during a clock cycle, the Port Chip select
(for Port A) and write/read select (for all ports) can change states during the
setup and hold time window of the cycle.
