(EF/OR) and Full Flag/Input Ready (FF/IR), and two programmable flags,
Almost-Empty (PAE) and Almost-Full (PAF). The offset loading of the
programmable flags is controlled by a simple state machine, and is initiated by
asserting the Load pin (LD). A Half-Full flag (HF) is available when the FIFO
is used in a single device configuration.

The synchronous FIFOs have two fixed flags, Empty Flag/Output Ready
There are two possible timing modes of operation with these devices: IDT
In IDT Standard Mode, the first word written to an empty FIFO will not appear

not have to be asserted for accessing the first word.
First Word Fall Through mode (FWFT). The XI and XO pins are used to expand
the FIFOs. In depth expansion configuration, First Load (FL) is grounded on
the first device and set to HIGH for all other devices in the Daisy Chain.
