Memory map

All the control parameters listed in the previous paragraphs are stored in the internal device

memory. Please refer to Table 12 and Table 13 for a complete list of their addresses.

For the programming procedure please refer to Section 6.24: User-defined coefficient

control registers (addr 0x27 - 0x37). Be aware that the read-all operation is not available for

the STC coefficients memory.

Table 12.
