Appendix A
Register Set
Bits D15 through D13 represent the device address in the cascade set by the automatic cascade detection described
in Section 2.1.13. In cascading, the master is the device directly connected to the DSP. For example, if there are four
devices in the cascade, as shown in row 4 of Table A-1 and in Section 2.7.5, the device address D15-D13 of the master
will have a binary value of 011. The other three slaves’ addresses are 010, 001, and 000, corresponding to their
positions in the cascade. The device address for a stand-alone device is always 000. Bits D11 through D8 comprise
the address of the register that is written with data carried in D7 through D0. D12 determines a read or write cycle
to the addressed register; a low selects a write cycle.
The following table shows the register map.
