H = High Steady State, L = Low Steady State, h = High voltage level one setup time prior to the Low-to-High clock transition, I = Low volt-
age level one setup time prior to the Low-to-High clock transition, X = Don’t Care,q = Lower case letters indicate the state of the referenced
output prior to the Low-to-High clock transition,
= Low-to-High Transition.
NOTES:
1. The TC output is High when TE is High and the counter is at Terminal Count (HHHH).
2. The High-to-Low transition of PE or TE should only occur while CP is High for conventional operation.
3. The Low-to-High transition of SPE should only occur while CP is High for conventional operation.
