100 / 175 page  WM8946 Production Data w PD, July 2012, Rev 4.3 100 Figure 42 3-Wire Serial Control Interface 4-WIRE (SPI) CONTROL MODE The 4-wire control interface uses the CS ¯¯ , SCLK, SDA and SDOUT pins. The Data Output pin, SDOUT, can be configured as CMOS or Open Drain, as described in Table 63. In CMOS mode, SDOUT is driven low when not outputting register data bits. In Open Drain mode, SDOUT is undriven (high impedance) when not outputting register data bits. In Write operations (R/W=0), this mode is the same as 3-wire mode described above. In Read operations (R/W=1), the SDATA pin is ignored following receipt of the valid register address. SDOUT is driven by the WM8946. The 4-wire control mode timing is illustrated in Figure 43 and Figure 44. Figure 43 4-Wire Readback (CMOS) Figure 44 4-Wire Readback (Open Drain) |
