14.3.1.2
The ORn registers define the sizes of memory banks and access attributes. The ORn attribute bits support
the following three modes of operation as defined by BRn[MSEL].
The ORn registers are interpreted differently depending on which of the three machine types is selected
for that bank.
14.3.1.2.1
The address mask fields of the option registers (ORn[XAM,AM]) mask up to 19 corresponding
BRn[BA,XBA] fields. The 15 lsbs of the 34-bit internal address do not participate in bank address
matching in selecting a bank for access. Masking address bits independently allows external devices of
different size address ranges to be used. Address mask bits can be set or cleared in any order in the field,
allowing a resource to reside in more than one area of the address map.
sizes from 32 Kbytes to 4 Gbytes. Note that the use of the ORn[XAM] fields provides 34-bits of internal
addressing which allows aliasing across 32-bit external banks.
