1.9 Allocation of resources

1.9.1 RAM address assignment

RAM address Address in hexadecimal
(TOM - xxxx) – TOM N.A.
1)
1024 kB – (TOM - xxxx) 100000 - N.A.
869 kB – 1024 kB 0E0000h - 0FFFFFh
768 kB – 896 kB 0C0000h - 0DFFFFh
640 kB – 768 kB 0A0000h - 0BFFFFh
639 kB – 640 kB 09FC00h - 09FFFFh
0 – 639 kB 000000h - 09FC00h
1) TOM = Top of memory: max. installed DRAM.
