TOGGLE BIT: In addition to DATA polling the AT29LV512 provides another method
for determining the end of a program or erase cycle. During a program or erase opera-
tion, successive attempts to read data from the device will result in I/O6 toggling
between one and zero. Once the program cycle has completed, I/O6 will stop toggling
and valid data will be read. Examining the toggle bit may begin at any time during a pro-
gram cycle.
OPTIONAL CHIP ERASE MODE: The entire device can be erased by using a 6-byte
software code. Please see Software Chip Erase application note for details.
