DATA
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/O7 (I/O0–I/O6
are indeterminate) until the programming cycle is com-
plete. 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 can
determine the completion of a write cycle, while a write
cycle is in progress, by reading data from the device.
This results in I/O6 toggling between one and zero. Once
the write is complete, however, I/O6 stops toggling and
valid data can be read from the device.
