NOTE A: For a read cycle, the last 8 bits are do-not-care bits.

Figure 3–4. Software FC Secondary Request (Phone Mode Disabled)

Table 3–3 shows the secondary communications format. D13 is the read/not-write (R/W) bit.

D12–D8 are address bits. The register map is specified in the register set section in Appendix A. D7–D0

are data bits. The data bits are the new values for the specified register addressed by D12–D8.
