* PRU_memAccessPRUDataRam.c
*
* The PRU reads and stores values into the PRU Data RAM memory. PRU Data RAM
* memory has an address in both the local data memory map and global memory
* map. The example accesses the local Data RAM using both the local address
* through a register pointed base address and the global address pointed by
* entries in the constant table.
