HFLOW.TheflagremainsLOWuntilthedifferencebetween
the write and read pointers becomes less than or equal to half of the total depth
of the device; the rising RCLK edge that accomplishes this condition sets
HF
HIGH.
InIDTStandardmode,ifnoreadsareperformedafterreset(
MRSorPRS),
HF will go LOW after (D/2 + 1) writes to the FIFO, where D = 65,536 for the
IDT72V36100 and 131,072 for the IDT72V36110.
In FWFT mode, if no reads are performed after reset (
MRS or PRS), HF
will go LOW after (D-1/2 + 2) writes to the FIFO, where D = 65,537 for the
IDT72V36100 and 131,073 for the IDT72V36110.
See Figure 22, Half-Full Flag Timing (IDT Standard and FWFT Modes),
for the relevant timing information. Because
HFisupdatedbybothRCLKand
WCLK, it is considered asynchronous.
DATA OUTPUTS (Q0-Qn)
(Q0-Q35) are data outputs for 36-bit wide data, (Q0 - Q17) are data outputs
for 18-bit wide data or (Q0-Q8) are data outputs for 9-bit wide data.
