SECTION 3
QUICC MEMORY MAP
The following tables present a programmer’s model (register map) of all registers in the
QUICC. For more information about a particular register, refer to the description for the mod-
ule or sub-module indicated in the right column. The address column indicates the offset of
the register from the address stored in the module base address register (MBAR). This reg-
ister in the SIM block controls the location of all internal memory/registers as well as their
supervisor/user access space (see Section 6 System Integration Module (SIM60)). Bold let-
ters mark registers that are restricted to supervisor access. Other registers are programma-
ble to exist in either supervisor or user space. Registers that are reset only by hard reset are
marked with an H in the reset value column. All of the registers are memory-mapped.
All internal memory and registers occupy a single 8-Kbyte memory block that is relocatable
along 8-Kbyte boundaries. The location is fixed by writing the desired base address of the
8-Kbyte memory block to the MBAR using the MOVES instruction. The MBAR is the only
exception since it resides at a fixed location in $03FF00.
The 8-Kbyte block is divided into two 4-Kbyte sections. The RAM occupies the first section;
the internal registers occupy the second section. The location of the QUICC registers is
shown in Figure 3-1.
