17.11.4 Memory Read Mode
• After the end of an auto-program, auto-erase, or status read operation, the command wait state
• Command writes can be performed in memory read mode, just as in the command wait state.
• Once memory read mode has been entered, consecutive reads can be performed.
• After power-on, memory read mode is entered.
