1.2.1.2 On-Chip Single-Access RAM (SARAM)
The SARAM is located at the CPU byte address range 01 0000h - 04FFFFh and is composed of 32 blocks
of 4K words each (see Table 1-3). Each SARAM block can perform one access per cycle (one read or one
write). SARAM can be accessed by the internal program, data, and DMA buses.
As shown in Table 1-3, the DMA controllers access SARAM at an address offset 0x0008_0000 from the
CPU memory byte address space.
