Autoselect Mode
The autoselect mode provides manufacturer and device identification, and sector
protection verification, through identifier codes output on DQ7–DQ0. This mode
is primarily intended for programming equipment to automatically match a device
to be programmed with its corresponding programming algorithm. However, the
autoselect codes can also be accessed in-system through the command register.
When using programming equipment, the autoselect mode requires
dress pin A9. Address pins must be as shown in Table 5. In addition, when
verifying sector protection, the sector address must appear on the appropriate
highest order address bits. Table
don’t care. When all necessary bits have been set as required, the programming
equipment may then read the corresponding identifier code on DQ7–DQ0. How-
ever, the autoselect codes can also be accessed in-system through the command
register, for instances when the S29JL032H is erased or programmed in a system
without access to high voltage on the A9 pin. The command sequence is illus-
trated in Table 13. Note that if a Bank Address (BA) on address bits A20, A19 and
A18 is asserted during the third write cycle of the autoselect command, the host
system can read autoselect data from that bank and then immediately read array
data from another bank, without exiting the autoselect mode.
To access the autoselect codes in-system, the host system can issue the autose-
lect command via the command register, as shown in Table 13. This method does
not require V
information.
