TIMING CONVENTIONS

hold time
The time interval during which a signal is retained at a specified input terminal after an active transition occurs
at another specified input terminal.
NOTES:
1. The hold time is the actual time interval between two signal events and is determined by the system in which the digital circuit
operates. A minimum value is specified that is the shortest interval for which correct operation of the digital circuit is assured.
2. The hold time can have a negative value in which case the minimum limit defines the longest interval (between the release
of the signal and the active transition) for which correct operation of the digital circuit is assured.

Description
Hold time, address, R/W and OCF from EDS, CSE1, CSE2, CSH1, CSH2,
CSH3, and CSPF high
Hold time, write data time from EDS high
Hold time, read time from EDS high
Hold time, WAIT time from SYSCLK high
Hold time, analog input from start of conversion

NOTE: The from-to sequence in the order of subscripts in the unclassified form is maintained in the classified form. In the case of hold times,
this causes the order to seem reversed from what would be suggested by the terms.
pulse duration (width)
The time interval between the specified reference points on the leading and trailing edges of the pulse
waveform.
