Notes: 1. All-erasure is performed. After that, the specified block can be erased.
• The user boot MAT can be programmed or erased only in boot mode and PROM mode.
• The user MAT and user boot MAT are erased in boot mode. Then, the user MAT and user boot
• The boot operation of the optional interface can be performed by the mode pin setting different
MAT can be programmed by means of the command method. However, the contents of the
MAT cannot be read until this state.
Only user boot MAT is programmed and the user MAT is programmed in user boot mode or
only user MAT is programmed because user boot mode is not used.
