USER’S MANUAL
The SIU allows the user to configure the system according to the particular require-
ments. The functions include control of show cycle operation, pin multiplexing, and in-
ternal memory map location. System configuration also includes a register containing
part and mask number constants to identify the part in software.
System configuration registers include the system configuration register (SIUMCR),
the internal memory mapping register (IMMR). Refer to
and Protection Registers
Some of the functions defined in the various sections of the SIU (external bus inter-
face, memory controller, and general-purpose I/O) share pins.
how the pin functions of these multiplexed pins are assigned.
The MPC555 / MPC556 internal memory space can be assigned to one of eight loca-
tions.
The internal memory map is organized as a single 4-Mbyte block. The user can assign
this block to one of eight locations by programming the ISB field in the internal memory
