1. 0 ns maximum for registers, and for Buffer Memory Port when port is ready before the write cycle begins. For port access only, 175 ns
maximum may occur if system makes contiguous system write cycles at less than 100 ns intervals, and both the transmitter and receiver
are active in “l(fā)oopback” reception.
2. 28 ns maximum for all registers. For port access only, 175 ns maximum may occur if system makes contiguous system write cycles at
less than 100 ns intervals, and both the transmitter and receiver are active in “l(fā)oopback” reception.
