Name and Function
WP#
INPUT
WRITE PROTECT:
Provides a method for unlocking the boot block in a system
without a 12 V supply.
When WP# is at logic low, the boot block is locked
, preventing program and
erase operations to the boot block. If a program or erase operation is attempted
on the boot block when WP# is low, the corresponding status bit (bit 4 for
program, bit 5 for erase) will be set in the status register to indicate the operation
failed.
When WP# is at logic high, the boot block is unlocked
and can be
programmed or erased.
NOTE:
This feature is overridden and the boot block unlocked when RP# is at
V
HH
. See Section 3.4 for details on write protection.
BYTE#
INPUT
BYTE# ENABLE:
Not available on
28F002B
. Controls whether the device
operates in the byte-wide mode (x8) or the word-wide mode (x16). BYTE# pin
must be controlled at CMOS levels to meet the CMOS current specification in the
standby mode.
When BYTE# is at logic low, the byte-wide mode is enabled
