The difference between the programming procedures in user program mode and user boot mode is
whether the MAT is switched or not as shown in figure 24.14.
In user boot mode, the user boot MAT can be seen in the flash memory space with the user MAT
hidden in the background. The user MAT and user boot MAT are switched only while the user
MAT is being programmed. Because the user boot MAT is hidden while the user MAT is being
programmed, the procedure program must be executed in an area other than flash memory. After
the programming procedure completes, switch the MATs again to return to the first state.
