The I
memory registers and the RAM definitions. In Table 5 the preliminary memory map is depicted. The hardware registers
are memory map on the XRAM of DSP2. Table 5 shows the detailed memory map of those locations. All locations are
acknowledged by the SAA7706H even if the user tries to write to a reserved space. The data in these sections will be
lost. Reading from this locations will result in undefined data words.
