USER’S MANUAL
Program the region base address in the L2U_RBAx registers to the lower boundary of
the region specified by the corresponding L2U_RAx[RS] field. If the region base ad-
dress does not correspond to the boundary of the block size programmed in the
L2U_RAx, the DMPU snaps the region base to the lower boundary of that block. For
example, if the block size is programmed to 16 Kbytes for region zero (i.e.
L2U_RA0[RS] = 0 x 3) and the region base address is programmed to 0x1FFF(i.e.,
L2U_RBA0[RBA] = 0 x 1), then the effective base address of region zero is 0 x 0. See
Figure
It is the user’s responsibility to program only legal region sizes. The L2U does not
check whether the value is legal. If the user programs an illegal region size, the region
calculation may not be successful.

The appropriate DMPU registers must be programmed before the
MSR[DR] bit is set. Otherwise, DMPU operation is not guaranteed.
