Configuration examples
The MPU module is designed for less complex memory management without TLB,
paging, dynamic allocation, and virtual memory. It provides lower power consumption
and no paging segmentation; therefore, an MPU is better suited for MCUs.

Configuration examples
6.1.4.1 Region descriptors setup
Example code:
#define TCML_BASE 0x20000000// Upper SRAM bitband region
#define TCML_SIZE 0x00010000
/* MPU Configuration */
MPU_RGD0_WORD2 = 0;// Disable RGD0
// Set RGD1
MPU_RGD1_WORD0 = 0;// Start address
MPU_RGD1_WORD1 = (TCML_BASE + TCML_SIZE);// End Address
MPU_RGD1_WORD2 = 0x0061F7DF;(No magic #’s)// Bus master 3: SM all access (List what the Bus
masters are in addition to #’s)
// Bus master 2: SM all access
// Bus master 2: UM all access
// Bus master 1: SM all access
// Bus master 1: UM all access
// Bus master 0: SM all access
// Bus master 0: UM all access
MPU_RGD1_WORD3 = 0x00000001;// region is valid
// Set RGD2
MPU_RGD2_WORD0 = (TCML_BASE + TCML_SIZE + 0x40);
MPU_RGD2_WORD1 = 0xFFFFFFFF;// End Address
MPU_RGD2_WORD2 = 0x0061F7DF;
MPU_RGD2_WORD3 = 0x00000001;// region is valid
// Enable MPU function
MPU_CESR = 0x00000001;
