"Illegal commands" include commands outside of the allowed command set (allowed commands: 40H [pgm], 20H [erase],
etc.)
If a "Read Array" is attempted from a busy partition, the result will be invalid data. The ID and CFI data are located at
different locations in the address map.
1st and 2nd cycles of "2 cycles write commands" must be given to the same partition address, or unexpected results will
occur.
To protect memory contents against erroneous command sequences, there are specific instances in a multi-cycle
command sequence in which the second cycle will be ignored. For example, when the device is program suspended and an
erase setup command (0x20) is given followed by a confirm/resume command (0xD0), the second command will be
ignored because it is unclear whether the user intends to erase the block or resume the program operation.
The Clear Status command only clears the error bits in the status register if the device is not in the following modes: WSM
running (Pgm Busy, Erase Busy, Pgm Busy In Erase Suspend, OTP Busy, BEFP modes).
BEFP writes are only allowed when the status register bit #0 = 0, or else the data is ignored.
