Address: 0x8008_0020 - Read/Write
Default: 0x0000_0000
Definition: PC Card Attribute register
Bit Descriptions:
The SMC has additional functionality to support a PC-card in Memory Bank 4. Memory Bank
4 has three registers to control wait-states and device width for attribute, common memory
and IO address spaces; and a single PCMCIA control register to provide global control for the
card.

EBI Break Disable - Read/Write
The value written to this bit specifies the circumstances for
when the SMC will release the external memory bus:
0 - The SMC releases the external memory bus at the end
of each access to this memory bank
1 - The SMC releases the external memory bus after it has
completed all pending accesses to this memory bank
Reserved - Unknown During Read
Attribute Space Width - Read/Write
The value written to this bit specifies the bus-width of the
Attribute space:
0 - 8-bit wide Attribute space
1 - 16-bit wide Attribute space
Attribute Space Access time - Read/Write
The value written to this field specifies the minimum
‘number of HCLK cycles, minus 1’ that the data strobe,
