PRODUCT PREVIEW
A Read Array/Program command can now be
written to the CUI to read/program data from/to
blocks other than that which is suspended. This
nested Program command can subsequently be
suspended to read yet another location. The only
valid commands while erase is suspended are
Read Status Register, Read Configuration, Read
Query, Program Setup, Program Resume, Erase
Resume, Lock Block, Unlock Block and Lock-Down
Block. During erase suspend mode, the chip can be
placed in a pseudo-standby mode by taking F-CE#
to V
IH
. This reduces active current consumption.
Erase Resume continues the erase sequence when
F-CE# = V
IL
. As with the end of a standard erase
operation, the status register must be read and
cleared before the next instruction is issued.

NOTES:
1.
Bus operations are defined in Table 2.
2.
Following the Read Configuration or Read Query commands, read operations output device configuration or CFI query
information, respectively.
3.
Either 40H or 10H command is valid, but the Intel standard is 40H.
4.
When writing commands, the upper data bus [DQ8
–DQ15] should be either V
IL
or V
IH
, to minimize current draw.
