26/65
During the program operation the memory will ignore all commands. It is not possible to
issue any command to abort or pause the operation. Typical program times are given in
Table Table 6.. Bus Read operations during the program operation will output the Status
Register on the Data Inputs/Outputs. See the section on the Status Register for more
details.
After the program operation has completed the memory returns to the Read mode, unless
an error has occurred. When an error occurs the memory continues to output the Status
Register. A Read/Reset command must be issued to reset the error condition and return to
Read mode.
Note that the Program command cannot change a bit set at ’0’ back to ’1’. One of the Erase
Commands must be used to set all the bits in a block or in the whole memory from ’0’ to ’1’.
4.4
Unlock Bypass Command.
The Unlock Bypass command is used in conjunction with the Unlock Bypass Program
command to program the memory. When the access time to the device is long (as with
some EPROM programmers) considerable time saving can be made by using these
commands. Three Bus Write operations are required to issue the Unlock Bypass command.
Once the Unlock Bypass command has been issued the memory will only accept the Unlock
Bypass Program command and the Unlock Bypass Reset command. The memory can be
read as if in Read mode.
4.5
Unlock Bypass Program Command.
The Unlock Bypass Program command can be used to program one address in memory at
a time. The command requires two Bus Write operations, the final write operation latches
the address and data, and starts the Program/Erase Controller.
The Program operation using the Unlock Bypass Program command behaves identically to
the Program operation using the Program command. A protected block cannot be
programmed; the operation cannot be aborted and the Status Register is read. Errors must
be reset using the Read/Reset command, which leaves the device in Unlock Bypass Mode.
See the Program command for details on the behavior.
4.6
Unlock Bypass Reset Command.
The Unlock Bypass Reset command can be used to return to Read/Reset mode from
Unlock Bypass Mode. Two Bus Write operations are required to issue the Unlock Bypass
Reset command. Read/Reset command does not exit from Unlock Bypass Mode.
4.7
Chip Erase Command.
The Chip Erase command can be used to erase the entire chip. Six Bus Write operations
are required to issue the Chip Erase Command and start the Program/Erase Controller.
If any blocks are protected then these are ignored and all the other blocks are erased. If all
of the blocks are protected the Chip Erase operation appears to start but will terminate
