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” .
