the end of a program or erase cycle. During a program or
erase operation, 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 tog-
gling and valid data will be read. Examining the toggle bit
may begin at any time during a program cycle.

in the following ways: (a) V
(typical), the program function is inhibited. (b) V
delay: once V
device will automatically time out 10 ms (typical) before
programming. (c) Program inhibit: holding any one of OE
low, CE high or WE high inhibits program cycles. (d) Noise
filter: pulses of less than 15 ns (typical) on the WE or CE
inputs will not initiate a program cycle.
