9.3.3 Address mapping from CPU to parallel programming mode
The following tables show the calculation from CPU addresses to flash macro addresses which are used in parallel programming.
Address mapping MB91F467Dx
Note: FA result is without 20:0000h offset for parallel Flash programming.
Set offset by keeping FA[21] = 1 as described in section “Parallel Flash programming mode”.
Address mapping MB91F465DA
Note: FA result is without 10:0000h offset for parallel Flash programming.
Set offset by keeping FA[20] = 1 as described in section “Parallel Flash programming mode”
