Comparison
The comparison table of programming and erasing related items about boot mode, user program

Notes: 1. All-erasure is performed. After that, the specified block can be erased.
2. Firstly, the reset vector is fetched from the embedded program storage MAT. After the
flash memory related registers are checked, the reset vector is fetched from the user
boot MAT.
•
The user boot MAT can be programmed or erased only in boot mode and programmer mode.
•
The user MAT and user boot MAT are erased in boot mode. Then, the user MAT and user
boot 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.
•
The boot operation of the optional interface can be performed by the mode pin setting
different from user program mode in user boot mode.
