Chapter 4 Memory Map
4.4 SRAM memory map
The on-chip RAM is split evenly among SRAM_L and SRAM_U. The RAM is also
implemented such that the SRAM_L and SRAM_U ranges form a contiguous block in
the memory map. See SRAM Arrays for details.
Accesses to the SRAM_L and SRAM_U memory ranges outside the amount of RAM on
the device causes the bus cycle to be terminated with an error followed by the appropriate
response in the requesting bus master.
4.5 Peripheral bridge (AIPS-Lite0 and AIPS-Lite1) memory
maps
The peripheral memory map is accessible via two slave ports on the crossbar switch in
the 0x4000_0000–0x400F_FFFF region. The device implements two peripheral bridges
(AIPS-Lite 0 and 1):
• AIPS-Lite0 covers 512 KB
• AIPS-Lite1 covers 508 KB with 4 KB assigned to the general purpose input/output
module (GPIO)
AIPS-Lite0 is connected to crossbar switch slave port 2, and is accessible at locations
0x4000_0000–0x4007_FFFF.
AIPS-Lite1 and the general purpose input/output module share the connection to crossbar
switch slave port 3. The AIPS-Lite1 is accessible at locations 0x4008_0000–
0x400F_EFFF. The general purpose input/output module is accessible in a 4-kbyte region
at 0x400F_F000–0x400F_FFFF. Its direct connection to the crossbar switch provides
master access without incurring wait states associated with accesses via the AIPS-Lite
controllers.
Modules that are disabled via their clock gate control bits in the SIM registers disable the
associated AIPS slots. Access to any address within an unimplemented or disabled
peripheral bridge slot results in a transfer error termination.
For programming model accesses via the peripheral bridges, there is generally only a
small range within the 4 KB slots that is implemented. Accessing an address that is not
implemented in the peripheral results in a transfer error termination.
