The MEMSS, or Memory Subsystem, covers the memory architecture used on the C29x platform. Each CPU has a 128-bit program bus, two 64-bit read buses, and a 64-bit write bus. RAM test and memory initialization can only be done from CPU1. Disable the dataline buffer using the enable bit in the MEM_DLB_CONFIG register before initializing memory or running the test mode to invalidate the last buffered data.
