INTERNAL MEMORY ACCESS AND VARIOUS CONTROL METHODS
Various controls can be performed by accessing the internal data memories of this LSI. This LSI has two built-in
DSPs (DSP_A and DSP_B), each of which is embedded with separate internal data memories.
The 8-bit registers CR6a–CR9a, which are mapped inside the control registers on the DSP_A side, are assigned to
the following for the purpose of accessing the internal data memory on the DSP_A side.
Similarly, the 8-bit registers CR6b–CR9b, which are mapped inside the control registers on the DSP_B side, are
assigned to the following for the purpose of accessing the internal data memories on the DSP_B side.
The following shows the methods of writing to and reading from the internal data memories. Moreover, Table 11
shows internal data memory lists.
Note that the following descriptions are given as common explanations of the DSP_A and DSP_B sides. To change
the internal data memories on the DSP_A side, acceess the control registers (CR0a–CR47a) on the DSP_A side, and
to change the internal data memories on the DSP_B side, access the control registers (CR0b–CR47b) on the DSP_B
side.
