A.1.8.3 Presence Detect High-Data Register
The presence detect high-data register is shown in Figure A–10. The register
stores the high-order bits of the presence detect data that was shifted in after
reset. Bits <15:0> in the register represent data bits <31:16> that were shifted
in.
Note
After deassertion of reset, it takes 148 system clock cycles for this data
to become valid.

A.1.8.4 Base Address Registers
Each memory bank set has a corresponding base address register as shown in
Figure A–11.

MBZ
The bits in this register are compared with the incoming sysBus address
sysadr<33:23> to determine the bank set being addressed. The contents of
this register are validated by setting the valid bit in the configuration register
of that bank set.
