Memory MAT switching is enabled by setting FMATS. However note that access to a memory
MAT is not allowed until memory MAT switching is completed. During memory MAT switching,
the LSI is in an unstable state, e.g. if an interrupt occurs, from which memory MAT the interrupt
vector is read is undetermined. Perform memory MAT switching in accordance with the
description in section 22.11, Switching between User MAT and User Boot MAT.
Except for memory 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 procedure program (on-chip RAM, user MAT,
and external space) is shown in section 22.8.4, On-Chip Program and Storable Area for Program
Data.
Note:
The MAT must be switched by FMATS to perform the erasing error processing in the user boot MAT.
