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 24.15.
MAT switching is enabled by writing a specific value to FMATS. Note, however, 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, and if an interrupt occurs, from which MAT the interrupt vector is
read is undetermined. Perform MAT switching in accordance with the description in section
24.10, Switching between User MAT and User Boot MAT.
