17.2.3
The comparison table of programming and erasing related items about boot mode and user
program mode is shown in table 17.2.
Table 17.2 Comparison of Programming Modes
Notes: 1. All-erasure is performed. After that, the specified block can be erased.
• The user MAT is all erased in boot mode. Then, the user MAT can be programmed by means
