¡ Semiconductor
• bit[5] SD: Other Dummy Cycle (read/write)
• bit[4] X: External Bus Clock Unit (read/write)
• bit[3:2] WT: Other Wait (read/write)
• bit[1:0] SZ: Other Device Size (read/write)
This bit sets whether or not a general device space access will immediately follow an SRAM space
or DRAM space read.
This bit will be "1" after reset.
This bit sets the operating clock unit for general device space.
This bit will be "0" after reset.
These bits set the wait count when general device space is accessed.
These bits will be "11" after reset.
These bits set the device size of general device space.
These bits will be "11" after reset. When this field is "00", attempting to access general device space
will cause an instruction access exception or data access exception.
