4 Start-Address High-Byte Registers
These registers contain the high nibble of the 16-bit memory window start address for memory windows 0, 1, 2, 3,
and 4. The lower 4 bits of these registers correspond to bits A23
–
A20 of the start address. In addition, the memory
window data width and wait states are set in this register. See Table 5
–
11 for a complete description of the register
contents.

FUNCTION
7
DATASIZE
RW
Data size. Bit 7 controls the memory window data width. This bit is encoded as:
0 = Window data width is 8 bits (default).
1 = Window data width is 16 bits.
6
ZEROWAIT
RW
Zero wait state. Bit 6 controls the memory window wait state for 8- and 16-bit accesses. This wait-state timing
emulates the ISA wait state used by the Intel
82365SL-DF. This bit is encoded as:
0 = 8- and 16-bit cycles have standard length (default).
1 = 8-bit cycles are reduced to equivalent of three ISA cycles.
16-bit cycles are reduced to equivalent of two ISA cycles.
