EMPTY FLAG (EF)
the read pointer is equal to the write pointer, indicating the device is empty.

PROGRAMMABLE ALMOST-FULL FLAG (PAF)
reaches the almost-full condition. If no reads are performed after Reset (RS),
the Programmable Almost-Full flag (PAF) will go LOW after (64-m) writes for the
IDT72421, (256-m) writes for the IDT72201, (512-m) writes for the IDT72211,
