Current Chip State
IS refers to Illegal State in the Next State Table.
“Illegal commands” include commands outside of the allowed command set.
The device defaults to "Read Array" on powerup.
If a “Read Array” is attempted when the device is busy, the result will be “garbage” data (we should not tell the user that
it will actually be Status Register data). The key point is that the output mux will be pointing to the “array”, but garbage
data will be output. “Read ID” and "Read Query" commands do the exact same thing in the device. The ID and Query data
are located at different locations in the address map.
The Clear Status command only clears the error bits in the status register if the device is not in the following modes:1.
WSM running (Pgm Busy, Erase Busy, Pgm Busy In Erase Suspend, OTP Busy, BEFP modes) 2. Suspend states (Erase
Suspend, Pgm Suspend, Pgm Suspend In Erase Suspend).
BEFP writes are only allowed when the status register bit #0 = 0 or else the data is ignored.
Confirm commands (Lock Block, Unlock Block, Lock-Down Block, Configuration Register and Blank Check) perform the
operation and then move to the Ready State.
Buffered programming will botch when a different block address (as compared to the address given on the first data write
cycle) is written during the BP Load1 and BP Load2 states.
All two cycle commands will be considered as a contiguous whole during device suspend states. Individual commands will
not be parsed separately. (I.e. If an erase set-up command is issued followed by a D0h command, the D0h command will
not resume the program operation. Issuing the erase set-up places the CUI in an “illegal state”. A subsequent command
will clear the “illegal state”, but the command will be otherwise ignored.
