Codes (High Voltage Method) table. In addition, when
verifying sector protection, the sector address must appear
on the appropriate highest order address bits. Refer to the
corresponding Sector Address Tables. The Command
Definitions table shows the remaining address bits that are
don't care. When all necessary bits have been set as
required, the programming equipment may then read the
corresponding identifier code on I/O7 - I/O0.To access the
autoselect codes in-system, the host system can issue the
autoselect command via the command register, as shown
in the Command Definitions table. This method does not
require VID. See "Command Definitions" for details on
using the autoselect mode.
Autoselect Mode
The autoselect mode provides manufacturer and device
identification, and sector protection verification, through
identifier codes output on I/O7 - I/O0. 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 VID (11.5V to 12.5 V) on address pinA9. Address
pins A6, A1, and A0 must be as shown in Autoselect
