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.
