Operating Modes or Product Identification.
The product identification mode identifies the device
DATA POLLING:
gram cycle. During a program cycle an attempted read of the last byte loaded will result
in the complement of the loaded data on I/O7. Once the program cycle has been com-
pleted, true data is valid on all outputs and the next cycle may begin. DATA polling may
begin at any time during the program cycle.
The AT29C256 features DATA polling to indicate the end of a pro-
TOGGLE BIT:
determining 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 toggling and valid
data will be read. Examining the toggle bit may begin at any time during a program
cycle.
In addition to DATA polling the AT29C256 provides another method for
OPTIONAL CHIP ERASE MODE:
software code. Please see Software Chip Erase application note for details.
The entire device can be erased by using a six-byte
