6.9.2.2 Programmable Range n End Address Register (PROGn_MPEAR)
The Programmable Address End Register holds the end address for the range. This register is writeable by a supervisor entity only.
The end address must be aligned on a page boundary. The size of the page depends on the MPU number. The page size for MPU1 is 1KB and for MPU2 it is 64KB. The size of the page determines the width of the address field in MPSAR and MPEAR. PROGn_MPEAR is shown in Figure 6-21 and described in Table 6-44.
