System Configuration and Protection
occupying the external bus. Internal bus arbitration is selected by clearing SIUMCR[EARB] (see
Section 6.2.2.1.1, “SIU Module Configuration Register
6.1.2.2
During an external master access, the USIU compares the external address with the internal address block
to determine if MPC561/MPC563 operation is required. Since only 24 of the 32 internal address bits are
available on the external bus, the USIU assigns zeros to the most significant address bits (ADDR[0:7]).
The address compare sequence can be summarized as follows:
When trying to fetch an MPC561/MPC563 special register from an external master, the address might be
aliased to one of the external devices on the external bus. If this device is selected by the
MPC561/MPC563 internal memory controller, this aliasing does not occur since the chip select is
disabled. If the device has its own address decoding or is being selected by external logic, this case is
resolved.
6.1.3
The USIU provides 64 general-purpose I/O (SGPIO) pins (See
multiplexed with the address and data pins. In single-chip mode, where communicating with external
devices is not required, all 64 SGPIO pins can be used. In multiple-chip mode, only eight SGPIO pins are
available. Another configuration allows the use of the address bus for instruction show cycles while the
data bus is dedicated to SGPIO functionality. The functionality of these pins is assigned by the single-chip
(SC) bit in the SIUMCR. (See
SGPIO pins are grouped as follows:

regions. If it finds a match, the memory controller generates the appropriate chip select and
attribute accordingly
