Reading the Configuration Table.
The configuration register can be read with a four-cycle com-
mand sequence. See
Table 13.1
for sequence details. Once the data has been read from the
configuration register, a software reset command is required to set the device into the correct
state.
8.4
Autoselect
The Autoselect is used for manufacturer ID, Device identification, and sector protection informa-
tion. This mode is primarily intended for programming equipment to automatically match a device
with its corresponding programming algorithm. The Autoselect codes can also be accessed in-sys-
tem. When verifying sector protection, the sector address must appear on the appropriate highest
order address bits (see
Table 8.9
). The remaining address bits are don't care. The most significant
four bits of the address during the third write cycle selects the bank from which the Autoselect
codes are read by the host. All other banks can be accessed normally for data read without exiting
the Autoselect mode.
To access the Autoselect codes, the host system must issue the Autoselect command.
