DATA Polling
DATA polling is provided to indicate the completion of
write cycle. Once a byte write or page write cycle is
initiated, attempting to read the last byte written will
output the complement of that data on I/O
7
(I/O
0
–I/O
6
are indeterminate) until the programming cycle is
complete. Upon completion of the self-timed write cycle,
all I/O’s will output true data during a read cycle.
Toggle Bit
In addition to the DATA Polling feature, the device offers
an additional method for determining the completion of
a write cycle. While a write cycle is in progress, reading
data from the device will result in I/O
6
toggling between
one and zero. However, once the write is complete, I/O
6
stops toggling and valid data can be read from the
device.
