46 / 127 page ![]() MB91460B Series Document Number: 002-04608 Rev. *A Page 45 of 126 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. 9.3.3.1 Address Mapping MB91F467BA 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 ”. 9.3.3.2 Address Mapping MB91F466BA 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 ”. CPU Address (addr) Condition Flash sectors FA (Flash address) Calculation 14:0000h to 14:FFFFh addr[2]==0 SA0, SA2, SA4, SA6 (8 Kbyte) FA := addr - addr%00:4000h + (addr%00:4000h)/2 - (addr/2)%4 + addr%4 - 05:0000h 14:0000h to 14:FFFFh addr[2]==1 SA1, SA3, SA5, SA7 (8 Kbyte) FA := addr - addr%00:4000h + (addr%00:4000h)/2 + 00:2000h - (addr/2)%4 + addr%4 - 05:0000h 04:0000h to 13:FFFFh addr[2]==0 SA8, SA10, SA12, SA14, SA16, SA18, SA20, SA22 (64 Kbyte) FA := addr - addr%02:0000 + (addr%02:0000h)/2 - (addr/2)%4 + addr%4 + 0C:0000h 04:0000h to 13:FFFFh addr[2]==1 SA9, SA11, SA13, SA15, SA17, SA19, SA21, SA23 (64 Kbyte) FA := addr - addr%02:0000h + (addr%02:0000h)/2 + 01:0000h - (addr/2)%4 + addr%4 + 0C:0000h CPU Address (addr) Condition Flash sectors FA (Flash address) Calculation 14:0000h to 14:FFFFh addr[2]==0 SA0, SA2, SA4, SA6 (8 Kbyte) FA := addr - addr%00:4000h + (addr%00:4000h)/2 - (addr/2)%4 + addr%4 - 05:0000h 14:0000h to 14:FFFFh addr[2]==1 SA1, SA3, SA5, SA7 (8 Kbyte) FA := addr - addr%00:4000h + (addr%00:4000h)/2 + 00:2000h - (ad- dr/2)%4 + addr%4 - 05:0000h 04:0000h to 0F:FFFFh addr[2]==0 SA8, SA10, SA12, SA14, SA16, SA18 (64 Kbyte) FA := addr - addr%02:0000 + (addr%02:0000h)/2 - (addr/2)%4 + ad- dr%4 + 0C:0000h 04:0000h to 0F:FFFFh addr[2]==1 SA9, SA11, SA13, SA15, SA17, SA19 (64 Kbyte) FA := addr - addr%02:0000h + (addr%02:0000h)/2 + 01:0000h - (ad- dr/2)%4 + addr%4 + 0C:0000h |
