– Alignment = 32-byte blocks
– Length = 32 bytes
Memory Range Descriptor #1
(two would be required for cards using
both ROM and shared RAM)
– 8-/16-bit, writable
– Minimum Base Address = 0x0C0000
– Maximum Base Address = 0x0FE000
– Alignment = 16-kbyte blocks
– Length = 16 kbytes
End Tag
– Covers all data bytes
