The MMSELR must be written by the CPU. Writing to MMSELR, the DMAC or PCIC module
must be set not to access to any resources, and all processing should be finished (for example, the
SYNCO instruction preceding the MOV instruction should be executed) before MMSELR is
modified.
In addition, execute the MOV instruction to read out MMSELR (a dummy read) twice and the
SYNCO instruction in succession immediately after a MOV instruction of write to MMSELR.
Example:
-----------------------------------------------------------------------
MOV.L #H'FF400020, R0 ;
MOV.L #MMSELR_DATA, R1 ; MMSELR_DATA=Writing value of MMSELR
SYNCO ; (upper word=H'A5A5)
MOV.L R1, @R0 ; Writing to MMSELR
MOV.L @R0, R2
MOV.L @R0, R2
SYNCO
