AC CHARACTERISTICS
Notes:
1. All status reads are 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.

Notes:
1. All status reads are 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.
