System Control Module (SCM)
8.3
The memory map for the SCM registers is shown in
memory-mapped as offsets within the 1 Gbyte IPS address space and accesses are controlled to these
registers by the control definitions programmed into the SACU.
8.4
8.4.1
The IPSBAR specifies the base address for the 1 Gbyte memory space associated with the on-chip
peripherals. At reset, the base address is loaded with a default location of 0x4000_0000 and marked as
valid (IPSBAR[V]=1). If desired, the address space associated with the internal modules can be moved by
loading a different value into the IPSBAR at a later time.
If an address “hits” in overlapping memory regions, the following priority is used to determine what
memory is accessed:
8-2
1. IPSBAR
2. RAMBAR
3. Cache
4. SDRAM
Memory Map and Register Definition
Register Descriptions
Internal Peripheral System Base Address Register (IPSBAR)
Accessing reserved IPSBAR memory space could result in an unterminated
bus cycle that causes the core to hang. Only a hard reset will allow the core
to recover from this state. Therefore, all bus accesses to IPSBAR space
should fall within a module’s memory map space.
