AC CHARACTERISTICS
Notes:
1. Status reads in figure are shown as asynchronous.
2. VA = Valid Address. Two read cycles are required to
determine status. When the Embedded Algorithm
operation is complete, and Data# Polling will output true
data.
3. AVD# must toggle between data reads.

Notes:
1. Status reads in figure are shown as asynchronous.
2. VA = Valid Address. Two read cycles are required to
determine status. When the Embedded Algorithm
operation is complete, the toggle bits will stop toggling.
3. AVD# must toggle between data reads.
