NOTES:
1. t
2. Depth is 512 for the IDT723631, 1,024 for the IDT723641, and 2,048 for the IDT723651.
3. FIFO write (CSA = LOW, W/RA = HIGH, MBA = LOW), FIFO read (CSB = LOW, W/RB = HIGH, MBB = LOW).
NOTE:
1. CSB = LOW, W/RB = HIGH, MBB = LOW. No input enables other than RTM and RFM are needed to control retransmit mode or begin a retransmit. Other enables are shown
NOTE:
1. X is the value loaded in the Almost-Empty flag Offset register.
