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,
3. While in Asynchronous mode, RDY will be low while the device is in embedded erase or programming mode.
