19.6.79 Memory24 (Memory Resource Descriptor Macro)
Syntax
Memory24 (ReadAndWrite, AddressMinimum, AddressMaximum, AddressAlignment,
RangeLength, DescriptorName)
Arguments
ReadAndWrite specifies whether or not the memory region is read-only (ReadOnly) or read/write
(ReadWrite). If nothing is specified, then ReadWrite is assumed. The 1-bit field
DescriptorName._RW is automatically created to refer to this portion of the resource descriptor,
where ‘1’ is ReadWrite and ‘0’ is ReadOnly.
AddressMinimum evaluates to a 16-bit integer that specifies bits [8:23] of the lowest possible base
address of the memory range. All other bits are assumed to be zero. The value must be an even
multiple of AddressAlignment. The 16-bit field DescriptorName._MIN is automatically created to
refer to this portion of the resource descriptor.
AddressMaximum evaluates to a 16-bit integer that specifies bits [8:23] of the highest possible base
address of the memory range. All other bits are assumed to be zero. The value must be an even
multiple of AddressAlignment. The 16-bit field DescriptorName._MAX is automatically created to
refer to this portion of the resource descriptor.
AddressAlignment evaluates to a 16-bit integer that specifies bits [0:15] of the required alignment for
the memory range. All other bits are assumed to be zero. The address selected must be an even
multiple of this value. The 16-bit field DescriptorName. _ALN is automatically created to refer to
this portion of the resource descriptor.
RangeLength evaluates to a 16-bit integer that specifies the total number of bytes decoded in the
memory range. The 16-bit field DescriptorName. _LEN is automatically created to refer to this
portion of the resource descriptor. The range length provides the length of the memory range in 256
byte blocks.
DescriptorName is an optional argument that specifies a name for an integer constant that will be
created in the current scope that contains the offset of this resource descriptor within the current
