5.18 ExCA Memory Windows 04 Offset-Address High-Byte Registers
These registers contain the high 6 bits of the 16-bit memory window offset address for memory windows 0, 1, 2, 3,
and 4. The lower 6 bits of these registers correspond to bits A25A20 of the offset address. In addition, the write
protection and common/attribute memory configurations are set in this register. See Table 513 for a complete
description of the register contents.

WINWP
RW
Write protect. This bit specifies whether write operations to this memory window are enabled.
This bit is encoded as:
0 = Write operations are allowed (default).
1 = Write operations are not allowed.
6
REG
RW
This bit specifies whether this memory window is mapped to card attribute or common memory.
This bit is encoded as:
0 = Memory window is mapped to common memory (default).
1 = Memory window is mapped to attribute memory.
50
OFFHB
RW
Offset-address high byte. These bits represent the upper address bits A25A20 of the memory window offset
address.
