20.1.2
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 20.1.
Table 20.1 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
• The boot operation of the optional interface can be performed by the mode pin setting different
