TOGGLE BIT: In addition to Data Polling the AT49BV802A(T) provides another method for determining the end of a program or erase cycle. During a program or erase operation, suc- cessive attempts to read data from the memory will result in l/06 toggling between one and zero. Once the program cycle has completed, 1/06 will stop toggling and valid data will be read. Examining the toggle bit may begin at any time during a program cycle. Please see "Sta- tus Bit Table" on page 10 for more details.
