on the LOW-to-HIGH transition of the Write Clock (WCLK). PAF is reset to HIGH
on the LOW-to-HIGH transition of the Read Clock (RCLK). If synchronous PAF
configuration is selected, the PAF is updated on the rising edge of WCLK. See

Standard and FWFT Mode).

when there are n words or less in the FIFO. The offset “n” is the empty offset
value. The default setting for this value is stated in Table 2.

HALF-FULL FLAG (HF)
beyond half-full sets HF LOW. The flag remains LOW until the difference between
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.
HF will go LOW after (D/2 + 1) writes to the FIFO. If x18 Input or x18 Output
bus Width is selected, D = 131,072 for the IDT72V2103 and 262,144 for the
IDT72V2113. If both x9 Input and x9 Output bus Widths are selected, D =
262,144 for the IDT72V2103 and 524,288 for the IDT72V2113.
