14.1.2
The comparison table of programming and erasing related items about boot mode, user program
mode, user boot mode, and programmer mode is shown in table 14.1.
Table 14.1 Comparison of Programming Modes
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 programmer mode.
• The user MAT and user boot MAT are erased in boot mode. Then, the user MAT and user boot
• There are some possible ways in this mode such as, writing only to the user boot MAT while

rewriting the user MAT in user boot mode, or rewriting only the user MAT due to not using
the user boot mode.
The boot operation of the optional interface can be performed by the mode pin setting different
from user program mode in user boot mode.
2. Firstly, the reset vector is fetched from the embedded program storage MAT. After the
