RESET

In the following situations, executing reset command will reset device back to read array mode:

• Among erase command sequence (before the full command set is completed)

• Sector erase time-out period

• Erase fail (while Q5 is high)

• Among program command sequence (before the full command set is completed, erase-suspended program

included)

• Program fail (while Q5 is high, and erase-suspended program fail is included)

• Read silicon ID mode

• Sector protect verify

While device is at the status of program fail or erase fail (Q5 is high), user must issue reset command to reset

device back to read array mode. While the device is in read silicon ID mode or sector protect verify mode, user

must issue reset command to reset device back to read array mode.

When the device is in the progress of programming (not program fail) or erasing (not erase fail), device will ig-

nore reset command.

AUTOMATIC SELECT COMMAND SEQUENCE

Automatic Select mode is used to access the manufacturer ID, device ID and to verify whether or not a sector is

protected. The automatic select mode has four command cycles. The first two are unlock cycles, and followed by

a specific command. The fourth cycle is a normal read cycle, and user can read at any address any number of

times without entering another command sequence. The reset command is necessary to exit the Automatic Se-

lect mode and back to read array. The following table shows the identification code with corresponding address.

There is an alternative method to that shown in Table 2, which is intended for EPROM programmers and requires

Vhv on address bit A9.
