Notes on Microprocessor Interface Read Timing:
1. Output propagation delay time is the time in nanoseconds from the 1.4 Volt
point of the reference signal to the 1.4 Volt point of the output.
2. Maximum output propagation delays are measured with a 100 pF load on the
Microprocessor Interface data bus, (D[7:0]).
3. A valid read cycle is defined as a logical OR of the CSB and the RDB signals.
4. In non-multiplexed address/data bus architectures, ALE should be held high
so parameters tSALR, tHALR, tVL, and tSLR are not applicable.
