The following are the data mode ID and the command
mode ID:
Operation

READ-MODIFY-WRITE
Data
1 0 1
COMMAND
Command
1 0 0
If successive commands have been issued, the com-
mand mode ID can be omitted. While the system is op-
erating in the non-successive command or the
non-successive address data mode, the CS pin should
be set to 1 and the previous operation mode will be re-
set also. The CS pin returns to 0 , a new operation
mode ID should be issued first.
