PROGRAMMABLE ALMOST-FULL FLAG (PAF
reaches the almost-full condition. In IDT Standard mode, if no reads are
performed after reset (MRS), PAF will go LOW after (D - m) words are written
to the FIFO. The PAF will go LOW after (32,768-m) writes for the IDT72V275
and (65,536-m) writes for the IDT72V285. The offset “m” is the full offset value.
The default setting for this value is stated in the footnote of Table 1.

PROGRAMMABLE ALMOST-EMPTY FLAG (PAE

HALF-FULL FLAG (HF

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.
