CALRAM Memory Map
The MPC561/MPC563 chip internal memory map is shown in
The CALRAM module is divided into two sections.
•
Control section:
— Includes all the registers in the CALRAM module
•
Array sub-region:
— Contains memory arrays
TheMPC561/MPC563 contains one CALRAM module — a 32-Kbyte memory at address 0x3F 8000 –
0x3F FFFF as shown in
and
. In addition, the module is assigned 16 32-bit register
address spaces: 12 implemented and four unimplemented registers. The 12 implemented registers are: one
module configuration register (CRAMMCR), one register reserved for factory test, eight region base
address (CRAM_RBAx) registers, one overlay configuration register (CRAMOVLCR), and one
ownership trace register (CALRAM_OTR) to support a separate module called READI. Refer to
