Note: The actual reset value of the ADDRSEL0 register is not relevant during external
boot modes, as the EBU_CON.CS0FAM bit is set to ensure that region 0 (i.e. CS0)
is activated for all external bus accesses. This allows external boot to be
performed from region 0 regardless of the actual boot address of the CPU to which
EBU is connected.

Base address to be compared to PLMB address in
conjunction with the mask control.
