The difference between the erasing procedures in user program mode and user boot mode depends

on whether the MAT is switched or not as shown in figure 21.15.

MAT switching is enabled by writing a specific value to FMATS. However note that while the

MATs are being switched, the LSI is in an unstable state, e.g. access to a MAT is not allowed until

MAT switching is completed finished, and if an interrupt occurs, from which MAT the interrupt

vector is read from is undetermined. Perform MAT switching in accordance with the description

in section 21.7.1, Switching between User MAT and User Boot MAT.

Except for MAT switching, the erasing procedure is the same as that in user program mode.

The area that can be executed in the steps of the user procedure program (on-chip RAM, user

MAT, and external space) is shown in section 21.8.2, Areas for Storage of the Procedural Program

and Data for Programming.
