The I
memory registers and the RAM definitions. In Table 8 the preliminary memory map is depicted. The hardware registers
are memory map on the XRAM of DSP. Table 9 shows the detailed memory map of those locations. All locations are
acknowledged by the SAA7715 even if the user tries to write to a reserved space. The data in these sections will be lost.
Reading from these locations will result in undefined data words.
