Following the Read Identifier or CFI Query commands, read operations output device identification data or CFI query
information, respectively. See
Either 0x40 or 0x10 command is valid, but the Numonyx standard is 0x40.
When writing commands, the upper data bus [DQ8-DQ15] should be either V
Command
A Read Array or Program command can now be issued 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 Identifier, CFI Query, Program
Setup, Program Resume, Erase Resume, Lock Block, Unlock Block, and Lock-Down
Block. During erase-suspend mode, the device can be placed in a pseudo-standby
mode by taking CE# to V
Erase Resume continues the erase sequence when CE# = V
standard Erase operation, the Status Register must be read and cleared before the next
instruction is issued.
