Boot Block Detection
In Autoselect mode, performing a read at
address 3CXX2H or address 0CXX2H will indicate
if the Top Boot Block sector or the Bottom Boot
Block sector is locked out. If the data is 01H, the
Top/Bottom Boot Block is protected. If the data is
00H, the Top/Bottom Boot Block is unprotected.
(see Table 3.)
Device ID
In Autoselect mode, performing a read at
address XXXXH will determine whether the device
is a Top Boot Block device or a Bottom Boot Block
device. If the data is 00H, the device is a Top Boot
Block. If the data is A0H, the device is a Bottom
Boot Block device (see Table 3).
In addition, the device ID can also be read via the
command register when the device is erased or
programmed in a system without applying high
voltage to the A
9
pin. When A
0
is HIGH, the device
ID is presented at the outputs.
Manufacturer ID
In Autoselect mode, performing a read at
address. XXXX0H will determine the manufacturer
ID. 40H is the manufacturer code for Mosel Vitelic
Flash.
In addition the manufacturer ID can also be read
via the command register when the device is
erased or programmed in a system without
applying high voltage to the A
9
pin. when A
0
is
LOW, the manufacturer ID is presented at the
outputs.
Hardware Data Protection
V
CC
Sense Protection:
the program operation is
inhibited when VCC is less than 2.5V.
Noise Protection:
a CE or WE pulse of less than
5ns will not initiate a program cycle.
Program Inhibit Protection:
holding any one of
OE LOW, CE HIGH or WE HIGH inhibits a program
cycle.
